Description

Technical Field

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

[0002] Concrete poles are poles made of concrete and reinforcing steel bars or wires. They are mainly used in power grid and communication construction. In the power grid, they are used to support and suspend power lines to ensure the stable and safe transmission of electricity. With the upgrading of power grids and the construction of mobile communications, concrete poles have been widely used in power grid lines and communication lines. Concrete poles are mostly monolithic cylindrical structures. In the actual application of concrete poles, it is necessary to improve their weather resistance to avoid damage caused by severe weather.

[0003] The lightweight, corrosion-resistant, high-strength concrete pole disclosed in application number CN202221809422.X is also an increasingly mature technology. The concrete pole is installed in the through groove inside the protective block through an installation mechanism. The bottom end of the protective block is then fixedly connected to a buried block. Several steel bars are fixedly connected at equal intervals on both the left and right ends of the buried block. The buried block and the steel bars are pre-embedded in the ground and reinforced with cement base and screws. This improves the corrosion resistance of the concrete pole, avoids surface cracking and peeling caused by wind and sun exposure, and makes the concrete pole more stable, thus increasing its service life.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist:

[0005] Because these concrete poles are integrally molded, they are inconvenient to operate and install, and are not easy to raise, which means that the entire pole needs to be replaced, which is both time-consuming and costly. Utility Model Content

[0006] The purpose of this utility model is to provide a weather-resistant concrete pole to solve the problems of the inconvenience and difficulty in raising the one-piece molded poles mentioned in the background art.

[0007] This utility model provides a weather-resistant concrete pole, including a base pole, with a pole body attached to the top of the base pole. Both the base pole and the pole body are coated with an anti-corrosion coating. Annular ribs are evenly spaced inside both the base pole and the pole body, and multiple straight ribs are arranged in a circumferential pattern inside each rib. A top ring is located near the top of the base pole, and a bottom ring is located near the bottom of the pole body. A sleeve is located at the bottom of the bottom ring and is inserted into the top of the base pole. Both the top and bottom rings have circumferential connecting holes on their surfaces, and long bolts are inserted into the connecting holes.

[0008] In this embodiment, the anti-corrosion coating has weather resistance, which can effectively resist the erosion of the two poles by natural environments such as rain and sunlight. Due to the intersecting of multiple straight ribs in the ring-shaped ribs, the compressive strength and bending stiffness of the poles can be enhanced, improving the overall structural stability of the two poles. Since the sleeve of the top ring is located at the top of the bottom pole, the top ring and the bottom ring are fixed by long bolts, which enhances the structural connection between the top and bottom of the two poles and ensures the stability of the docking installation of the two poles.

[0009] In one embodiment of this utility model, a fixing ring is provided at the bottom end of the base pole, and a through hole is provided on the surface of the fixing ring. A groove is provided inside the bottom end of the base pole, and a convex positioning ring is movably inserted inside the groove. A screw rod is fixedly connected to the top end of the positioning ring, and the screw rod is inserted into the through hole and fixed by a nut. A positioning hole is provided on the surface of the positioning ring, and a positioning pin is movably inserted inside the positioning hole.

[0010] In this solution, the screw rod at the top of the convex positioning ring is aligned with the through hole of the fixing ring, and the positioning ring and screw rod are inserted into the groove of the bottom electric rod and the through hole of the fixing ring. The bottom electric rod is tightened by rotating the nut, so that the bottom electric rod and the positioning ring are firmly connected. The positioning hole is used to lock the position through the internal positioning pin.

[0011] In one embodiment of this utility model, a fixing iron ring is provided at the top of the pole body, and two sets of fixing iron rings are fixed by bolts. L-shaped strips are welded to both outer sides of the fixing iron rings, and a fixing rod is provided at the top of each L-shaped strip and an insulator is connected to the top of the rod.

[0012] In this solution, the fixing ring is fixedly connected by bolts, and the L-shaped plate is used to support the fixing rod and the insulator to support the wire. The insulator effectively reduces the risk of leakage at the top of the pole.

[0013] In one embodiment of this utility model, a cylinder is fixedly connected to the bottom center of the positioning ring, and a steel rod is arranged in a ring on the surface of the cylinder, with the steel rod and the positioning pin arranged alternately.

[0014] In this design, steel rods are installed on the cylindrical surface to reinforce and fix the bottom of the positioning ring around the perimeter with cement base stones and positioning nails, making the base of the pole more stable.

[0015] In one embodiment of this utility model, the fixing ring and the top ring of the bottom pole are provided with reinforcing ribs in a ring shape at their opposite ends and at the top of the bottom ring of the pole body.

[0016] In this design, the reinforcing ribs ensure that the load is evenly distributed across the components, thereby enhancing the connection performance and stability of each link.

[0017] In one embodiment of this utility model, the inner sidewalls of the fixing iron ring are all provided with rubber rings, and the diameter of the positioning ring is larger than that of the fixing ring.

[0018] In this design, the friction between the fixing iron ring and the surface of the pole body is increased by using a rubber ring, and the diameter of the positioning ring is larger than that of the fixing ring, which helps to provide more stable support.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) Align the screw rod at the top of the convex positioning ring with the through hole of the fixing ring, and insert the positioning ring and screw rod into the groove of the bottom electric rod and the through hole of the fixing ring. Tighten the bottom electric rod by rotating the nut to make the bottom electric rod and the positioning ring firmly connected. The positioning hole is used to lock the position through the internal positioning pin to ensure the stability of the positioning ring position. A steel rod is provided on the cylindrical surface to reinforce and fix the bottom of the positioning ring with cement base stone and positioning pin, making the base of the bottom electric rod more stable and improving the service life of the positioning ring.

[0021] (2) The sleeve of the top ring is located at the top of the bottom pole. The top ring and the bottom ring are fixed by long bolts, which enhances the structural connection between the top and bottom of the two poles and ensures the stability of the two poles. The pole body is installed at the top of the bottom pole, which facilitates the lifting of the bottom pole and avoids the inconvenience of transporting and installing the one-piece pole. The anti-corrosion coating is weather resistant and can effectively resist the erosion of the two poles by natural environment such as rain and sunlight. Due to the cross of the ring ribs and multiple straight ribs, the compressive strength and bending stiffness of the pole can be enhanced, and the overall structural stability of the two poles can be improved. The ring ribs improve the strength of the pole under lateral force and enhance the bending ability of the pole. The straight ribs improve the tensile strength and ensure the stability of the pole under vertical or lateral loads such as wind and snow. Attached Figure Description

Both the base pole 100 and the pole body 110 are coated with an anti-corrosion coating. Both the base pole 100 and the pole body 110 have evenly spaced annular ribs 111 inside. Multiple straight ribs 112 are arranged in a ring-shaped pattern inside the annular ribs 111. A top ring 114 is provided near the top of the base pole 100, and a bottom ring 115 is provided near the bottom of the pole body 110. A sleeve 116 is provided at the bottom of the bottom ring 115 and is inserted into the top of the base pole 100. Both the top ring 114 and the bottom ring 115 have annular connecting holes 117, and long bolts 118 are inserted into the surface of the connecting holes 117.

[0032] In one specific embodiment, please refer to Figure 2 and Figure 3The pole body 110 is installed at the top of the bottom pole 100, which facilitates the raising of the height of the bottom pole 100 and avoids the inconvenience of transporting and installing a one-piece pole. The anti-corrosion coating is weather-resistant and can effectively resist the erosion of the two poles by natural environments such as rain and sunlight. Due to the intersection of the ring-shaped ribs 111 and multiple straight ribs 112, the compressive strength and bending stiffness of the pole can be enhanced, improving the overall structural stability of the two poles. The ring-shaped ribs 111 improve the strength of the pole under lateral force and enhance the bending capacity of the pole. The straight ribs 112 improve the tensile strength and ensure the stability of the pole under vertical or lateral loads such as wind and snow. Since the sleeve 116 of the top ring 114 is located at the top of the bottom pole 100, the top ring 114 is fixed by long bolts 118, which enhances the structural connection between the top and bottom of the two poles and ensures the stability of the two poles.

[0033] Please see Figure 2 The bottom end of the base pole 100 is provided with a fixing ring 119. The surface of the fixing ring 119 is provided with a through hole 120. The bottom end of the base pole 100 is provided with a groove 121. A convex positioning ring 122 is movably inserted inside the groove 121.

The surface of the positioning ring 122 is provided with a positioning hole 124. A positioning pin 125 is movably inserted inside the positioning hole 124.

[0034] In one specific embodiment, please refer to Figure 2 The screw rod 123 at the top of the convex positioning ring 122 is aligned with the through hole 120 of the fixing ring 119, and the positioning ring 122 and the screw rod 123 are inserted into the groove 121 of the bottom electric rod 100 and the through hole 120 of the fixing ring 119. The bottom electric rod 100 is tightened by rotating the nut, so that the bottom electric rod 100 and the positioning ring 122 are firmly connected. The positioning hole 124 is used to lock the position through the internally inserted positioning pin 125 to ensure the stability of the position of the positioning ring 122.

[0035] Please see Figure 3 The top of the pole body 110 is provided with a fixing iron ring 126. Two sets of fixing iron rings 126 are fixed by bolts. L-shaped strips 127 are welded to both sides of the outer side of the fixing iron ring 126. The top of the L-shaped strips 127 is provided with a fixing rod and an insulator 128 is connected to the top.

[0036] In one specific embodiment, please refer to Figure 3 The fixing ring 126 is fixedly connected by bolts. The long rod bolt 118 is used to support the fixing rod and the insulator 128 so as to support the wire. The insulator 128 effectively reduces the risk of leakage at the top of the power pole and ensures the safe operation of the power system.

[0037] Please see Figure 2 A cylinder 129 is fixedly connected to the bottom center of the positioning ring 122. A steel rod 130 is arranged in a ring on the surface of the cylinder 129. The steel rod 130 and the positioning pin 125 are arranged alternately.

A steel rod 130 is provided on the surface of the cylinder 129 to reinforce and fix the bottom of the positioning ring 122 with cement base and positioning pin 125, so that the base of the bottom electric rod 100 is more stable and the service life of the positioning ring 122 is improved. Since the sleeve 116 of the top ring 114 is located on the bottom electric rod At the top of pole 100, the top ring 114 and the bottom ring 115 are fixed by long bolts 118, which enhances the structural connection between the top and bottom of the two poles and ensures the stability of the two poles. The top of the bottom pole 100 is connected to the pole body 110, which facilitates the raising of the height of the bottom pole 100 and avoids the inconvenience of transporting and installing the one-piece pole. The anti-corrosion coating is weather-resistant and can effectively resist the erosion of the two poles by natural environment such as rain and sunlight. Due to the intersection of the ring ribs 111 and multiple straight ribs 112, the compressive strength and bending stiffness of the pole can be enhanced, and the overall structural stability of the two poles can be improved. The ring ribs 111 improve the strength of the pole under lateral force and enhance the bending capacity of the pole, while the straight ribs 112 improve the resistance to bending.
