Detailed implementation manners

[0026] A cement pole is a power equipment support pole made mainly of cement, sand, and gravel through a centrifugal molding or casting process, and usually has a steel bar skeleton inside to enhance the structural strength. Its cross-sectional forms include circular, square, octagonal, etc., and it has the characteristics of high strength, corrosion resistance, and strong weather resistance, and is suitable for various complex environments.

[0027] As the core support structure of power lines, cement poles are widely used in high-voltage transmission lines, urban power grids, and rural power grids, undertaking the crucial task of delivering electrical energy from power plants to end-users. Their sturdy and durable characteristics ensure the long-term stable operation of power lines. With the development of communication technology, cement poles have gradually become important carriers for communication lines. Their high strength and weather resistance enable them to stably support devices such as telephone lines, Internet optical fibers, and mobile signal towers, ensuring the smoothness of the communication network. In the railway field, cement poles are used to support electrification equipment such as catenaries and signal lines. Their height and shape can be customized according to the needs of railway lines to ensure the stability and safety of the train power supply system. In areas prone to natural disasters such as typhoons and floods, cement poles, with their wind and earthquake resistance capabilities, become the preferred facilities for power restoration. In addition, in harsh environments such as remote mountainous areas and deserts, their durability ensures the reliability of power supply. Technical advantages of cement poles: High strength and durability: The reinforced concrete structure enables them to withstand extreme weather such as strong winds, ice, and snow. Corrosion resistance: The cement material effectively resists corrosive environments such as acid rain and salt spray. Environmental protection and energy conservation: The production process is low-carbon and environmentally friendly, with a long service life, reducing resource waste. Economy: Compared with wooden or metal poles, cement poles have lower costs and less maintenance expenses.

A plurality of power storage devices are evenly installed on the surface of the column body, and a clamping device is sleeved on the outer surface of the column body near the end. The power storage device includes a support frame, a power storage mechanism, a limiting cylinder, a connecting plate, a traction rod, an auxiliary block, a support plate and a lifting mechanism. The support frame is installed on the surface of the column body through a support column. The support frame is of a U-shaped structure. A plurality of power storage mechanisms are evenly installed in the middle of the end of the support frame away from the column body. A plurality of sliding holes are evenly opened on the side wall of the support frame. The limiting cylinder is connected inside the sliding hole by a sliding fit. One end of the limiting cylinder away from the power storage mechanism is installed with a connecting plate. Traction rods are symmetrically arranged outside the power storage mechanism. One end of the traction rod close to the power storage mechanism is rotatably connected to the power storage mechanism. An auxiliary block is arranged below the traction rod. The auxiliary block is fixedly connected to the side wall of the support frame. The middle of the auxiliary block is connected with the support plate by a sliding fit. A lifting mechanism is arranged on the side of the support frame close to the column body. The lifting mechanism is installed on the outer surface of the column body. Specifically, during operation, first, the clamping device is sleeved on the surface of the column body manually and lifted by mechanical assistance. The clamping device drives the column body to move to the installation location, and the column body is installed and fixed manually. After that, the support plate is pulled open manually, and the traction rod is pulled manually. The traction rod drives the power storage mechanism to rotate to form a staircase, so as to facilitate the construction personnel to climb to the upper end of the column body and install and repair the wires. Finally, after the installation or repair of the wires is completed, the power storage mechanism is driven to reset by the traction rod manually. The connecting plate is pulled open manually, and the limiting of the lower end of the power storage mechanism by the connecting plate is released through the limiting cylinder. The lifting mechanism is rotated manually, and the lifting mechanism drives the power storage mechanism to be lifted, so as to change the angle of the power storage mechanism, facilitate the utilization of light energy by the power storage mechanism, and improve the use efficiency of the power storage mechanism. The power storage mechanism includes an installation block, a rotating rod, a rotating shaft rod, a pin shaft block, a placement frame and a solar panel. The installation block is installed in the middle of the end of the support frame away from the column body. The lower end of the installation block is connected with the rotating rod by a pin shaft. One end of the rotating rod away from the installation block is connected with the rotating shaft rod by a pin shaft. One end of the rotating shaft rod away from the rotating rod is rotatably connected to the pin shaft block. One end of the pin shaft block away from the installation block is installed with a placement frame. A solar panel is installed inside the placement frame. Round rods are symmetrically installed on the outer surface of the side wall of the placement frame near the lower end. The round rods are in sliding fit with the limiting cylinder. The outer surface of the side wall of the placement frame near the upper end is connected with the traction rod by a pin shaft. Specifically, during the installation and repair of the wires, the traction rod is pulled manually. The traction rod drives the solar panel to rotate through the placement frame to form a staircase. After that, after the installation and repair of the wires are completed, the placement frame is driven to reset by the traction rod manually. The lifting mechanism is rotated manually, and the solar panel is lifted through the placement frame by the lifting mechanism, so as to adjust the angle of the solar panel, facilitate the solar panel to receive solar energy, and the rotating rod and the rotating shaft rod play the functions of connection and angle change.A plurality of rectangular grooves are evenly formed at one end of the drawbar close to the electricity storage mechanism. The rectangular grooves are in sliding fit with the round rod. During specific operation, after the wire is maintained and installed, an operator rotates the adjusting screw rod manually. The adjusting screw rod drives the lifting plate to move through the square plate. The lifting plate drives the slider to move through the slide rail rod. The slider drives the placement frame to rotate through the jacking arc rod. The rectangular grooves prevent the round rod from being jacked out, ensuring the rotation of the solar panel.

[0029] The jacking mechanism includes an auxiliary plate, an adjusting screw, a lifting plate, a slide rail rod, a slider, a connecting spring and a jacking arc rod. The auxiliary plate is installed on the outer surface of the column. The middle of the auxiliary plate is connected through thread fitting with the adjusting screw. The upper end of the adjusting screw is connected with a square plate through a bearing. One end of the square plate close to the column is installed with a lifting plate. A plurality of slide rail rods are evenly installed at one end of the lifting plate away from the column. The outer surface of the slide rail rod is sleeved and connected with a slider. A circular plate is installed at one end of the slide rail rod away from the lifting plate. A connecting spring is sleeved outside the slide rail rod. One end of the connecting spring is fixedly connected with the slider, and the other end of the connecting spring is fixedly connected with the circular plate. The lower end of the slider is connected with the jacking arc rod through a pin shaft. The jacking arc rod is in sliding fit with the support frame. During specific operation, the adjusting screw is rotated manually. The adjusting screw drives the lifting plate to move through the square plate. The lifting plate drives the slider to move through the slide rail rod. The slider drives the jacking arc rod to descend, so as to jack up the solar panel and change the angle of the solar panel for adjustment, facilitating the solar panel to receive solar energy. When repairing and installing the electric wire, the adjusting screw is rotated manually. The adjusting screw drives the lifting plate to rise through the square plate, thus driving the lifting arc rod to reset. The clamping device includes a clamping ring, a sliding rod, a clamping plate, a clamping spring, a pulling rod and a pushing block. The clamping rings are symmetrically sleeved on the outer surface of the column. A plurality of rectangular through holes are evenly opened inside the clamping ring. A slide hole is opened on the side wall of the rectangular through hole close to the column. The slide hole is internally connected with a sliding rod through sliding fit. One end of the sliding rod close to the column is installed with a clamping plate. A plurality of triangular teeth are evenly arranged at one end of the clamping plate close to the column. One end of the clamping plate away from the column is fixedly installed with a clamping spring. The end of the clamping spring away from the clamping plate is fixedly connected with the clamping ring. The pulling rod is connected inside the rectangular through hole through sliding fit. A pushing block is arranged on one side of the sliding rod away from the clamping plate. The pushing block is fixedly connected with the pulling rod. The pushing block is in a right trapezoidal structure. During specific operation, first, the clamping ring is sleeved on the surface of the column manually. Then, the pulling rod is hoisted by mechanical assistance. The pulling rod drives the sliding rod to be pushed through the pushing block. The sliding rod clamps the surface of the column through the clamping plate. Moreover, the triangular teeth increase the friction between the clamping plate and the surface of the column, thus avoiding the phenomenon of the column slipping during hoisting, reducing the installation risk, improving the installation success rate and avoiding the damage of the column. The clamping ring drives the column to move to the installation place, and the column is installed and fixed manually. Finally, the pulling rod is inserted into the land at the column by mechanical assistance, avoiding the phenomenon of the column tilting, thus improving the stability of the column.

[0030] The clamping ring includes semi-circular rings, threaded plates and locking screws. The semi-circular rings are symmetrically sleeved on the outer surface of the column body. The threaded plates are symmetrically installed on the outer sides of the semi-circular rings. The middle parts of the threaded plates are threadedly connected with the locking screws. During specific operation, the semi-circular rings are sleeved on the outer surface of the column body manually. Then, the locking screws are rotated manually. The locking screws lock and fix the semi-circular rings, thereby realizing the function of clamping the column body, facilitating the hoisting of the column body, avoiding the phenomenon of the column body slipping during hoisting, and reducing the installation risk. One end of the sliding rod away from the clamping plate is provided with an inclined surface, which is in sliding fit with the pushing block. During specific operation, the pulling rod is hoisted by mechanical assistance. The pulling rod cooperates with the inclined surface on the sliding rod through the pushing block, thereby driving the clamping plate to clamp the surface of the column body, avoiding the phenomenon of the column body slipping during hoisting, and reducing the installation risk. A hoisting hole is opened near the upper end inside the pulling rod. A triangular protrusion is integrally formed at the lower end of the pulling rod. During specific operation, the pulling rod is hoisted by mechanical assistance. The pulling rod cooperates with the inclined surface on the sliding rod through the pushing block, thereby driving the clamping plate to clamp the surface of the column body, thereby realizing the function of hoisting the column body. After the hoisting is completed, the pulling rod is pressed by mechanical assistance. The pulling rod inserts into the ground through the triangular protrusion, thereby improving the stability of the column body.

[0031] Known, the existing patent discloses a spliced cement pole with the application number 202111398621.6, which includes a pole body, a connecting piece, a guiding piece and a guiding sleeve; connecting pieces are symmetrically arranged at the upper and lower ends of the pole body; the connecting pieces are cast together with the pole body; the connecting pieces are fixedly connected to the steel bar framework inside the pole body; guiding pieces are evenly spaced at one end of the pole body; the guiding pieces are fixedly connected to the pole body; a guiding sleeve is arranged at the other end of the pole body; the guiding sleeve is cast together with the pole body; the guiding sleeves correspond to the guiding pieces one by one. During operation, fix one pole body on the ground (it can be fixed by deep embedding or by fixedly connecting with a pre-embedded base), lift another pole body (the pole body to be installed) by a lifting device, make the pole body to be installed in a vertical state, and the ends of the two pole bodies with guiding pieces face upward or downward simultaneously. Stop moving upward after the lower end of the pole body to be installed is higher than the upper end of the installed pole body. Then adjust the position of the pole body to be installed to align the guiding pieces of one pole body with the guiding sleeves of the other one by one. After all the guiding pieces and guiding sleeves of the two pole bodies are aligned, use the lifting device to slowly move the pole body to be installed downward. When the pole body to be installed moves downward, all the guiding pieces on one pole body respectively enter the corresponding guiding sleeves of the other pole body. Furthermore, through the guiding function of the guiding pieces and guiding sleeves, the pole body to be installed is straightened, so that the axis of the pole body to be installed is on the same straight line as the axis of the installed pole body, thus completing the centering work of the two pole bodies. Then continue to move the pole body to be installed downward until the connecting piece of the pole body to be installed abuts against the connecting piece of the installed pole body. Then weld the connecting piece of the pole body to be installed to the connecting piece of the installed pole body, thereby fixing the connecting pieces of the two pole bodies together. Then repeat the above work until all the pole bodies are installed, thus completing the installation of the poles;At present, when extending a cement pole, a special tooling fixture is required for centering. When using the tooling fixture in the air, the operation is rather difficult, which increases the centering difficulty of the cement pole, the extension difficulty of the cement pole, and the installation difficulty of the cement pole, making it inconvenient for the installation of the cement pole. Moreover, the large centering difficulty results in poor centering quality of the cement pole, leading to poor overall strength of the cement pole and increasing the risk of the cement pole breaking. However, for this cement pole, through the guiding action of the guiding member and the guiding sleeve, the centering work of two pole bodies is automatically completed during the downward movement of the pole body to be installed, thus avoiding the use of a tooling fixture for centering, reducing the operation difficulty, reducing the centering difficulty of the pole body, facilitating the centering of the pole body, facilitating the extension of the pole body, and facilitating the installation of the cement pole. At the same time, the centering quality of the pole body is improved, the position accuracy of the pole body is improved, the overall straightness of the cement pole is improved, the overall strength of the cement pole is improved, the risk of the cement pole breaking is reduced, and the reliability of the cement pole is improved; after the centering of the pole body, the two connecting members are welded together, thus quickly completing the connection of the pole body, and the welding will not reduce the contact area of the two connecting members, thus increasing the stress area of the connecting members, increasing the supporting capacity of the connecting members, improving the stability of the connection, improving the stability of the cement pole, improving the overall strength and stability of the cement pole, improving the reliability of the cement pole, and improving the reliability of the power system; through the fixed connection between the connecting member and the steel bar cage, the surface of the connecting member is perpendicular to the axis of the steel bar cage, thus making the connecting member perpendicular to the axis of the pole body. After the surfaces of the two connecting members are mutually attached, the axis of the pole body is in a vertical state, thus improving the vertical degree of the pole body, reducing the inclination degree of the pole body, reducing the inclination degree of the cement pole, improving the ability of the cement pole to resist lateral forces, improving the stability of the cement pole, improving the reliability of the cement pole, and improving the reliability of the power system.;

[0032] The strength of the guiding member gradually decreases along the length direction; the strength of the guiding member at the end far from the pole body is less than that at the end close to the pole body. When the pole body to be installed moves downward, due to the long length of the pole body, the pole body to be installed will be inclined, and it is impossible for all guiding members to enter the corresponding guiding sleeves simultaneously. It is necessary to use other tools to make the pole body in a relatively vertical state so that all guiding members can enter the corresponding guiding sleeves simultaneously, increasing the difficulty of centering. By setting the guiding member with the strength at the end far from the pole body less than that at the end close to the pole body, the guiding member at the end far from the pole body is prone to deformation, thus facilitating the guiding member to enter the corresponding guiding sleeve, thus facilitating all guiding members to enter the corresponding guiding sleeves simultaneously, thus facilitating the centering of the two pole bodies, thus facilitating the connection of the two pole bodies, and thus facilitating the installation of the cement pole; as the pole body to be installed moves downward, the length of the guiding member entering the guiding sleeve becomes longer and longer, thus the strength at the contact between the guiding member and the guiding sleeve gradually increases, thus increasing the acting force between the guiding member and the guiding sleeve, thus increasing the guiding effect between the guiding member and the guiding sleeve, thus increasing the centering effect of the pole body to be installed, thus improving the centering quality of the pole body, thus improving the position accuracy of the pole body of the pole, thus improving the overall straightness of the cement pole, thus improving the overall strength of the cement pole, thus improving the reliability of the cement pole, and thus improving the reliability of the power system. The guiding member includes a connecting seat and a guiding rod; the connecting seat is fixedly connected to the pole body; a guiding rod is arranged in the connecting seat; the guiding rods are arranged at equal intervals; the diameter of the guiding rod gradually decreases along the axial direction of the guiding rod; the end of the guiding rod with a larger diameter is fixedly connected to the connecting seat. By arranging the guiding rods at equal intervals in the connecting seat and the diameter of the end of the guiding rod far from the connecting seat is smaller than that of the other end, the end of the guiding rod far from the connecting seat is prone to deformation, thus facilitating the guiding rod to enter the guiding sleeve, thus facilitating the guiding member to enter the guiding sleeve. Because the diameter of the end of the guiding rod far from the connecting seat is smaller than that of the other end, the distance between the ends of the guiding rods is increased, thus increasing the deformation amount of the ends of the guiding rods, reducing the overall size of the guiding member at the end far from the connecting seat, thus making it easier for the guiding member to enter the guiding sleeve, and thus improving the convenience of centering; when the guiding rods are concentrated together, they have a great overall strength, thus while facilitating the guiding member to enter the guiding sleeve, making the guiding member have a great overall strength, thus increasing the acting force of the guiding member on the guiding sleeve, thus increasing the guiding effect between the guiding member and the guiding sleeve, thus improving the centering quality of the pole body, thus improving the overall strength of the cement pole, thus improving the reliability of the cement pole, and thus improving the reliability of the power system.

[0033] The guide sleeve is provided with grouting holes; the pole body is provided with a grouting channel; the grouting channel is communicated with the grouting holes; the grouting holes and the grouting channel are used for grouting. By setting the grouting channel and the grouting holes, the slurry is then pressed into the guide sleeve through the grouting channel and the grouting holes, so that the space between the guide sleeve and the two pole bodies is filled with the slurry. After the slurry solidifies, the adjacent two pole bodies are connected into a whole, thereby increasing the connection strength between the adjacent two pole bodies, increasing the strength of the cement pole, improving the reliability of the cement pole, and after the slurry solidifies, the slurry can provide a supporting force, thereby improving the supporting capacity of the connection, improving the stability of the connection, and improving the stability of the cement pole; the slurry wraps the guide, the guide sleeve and the connecting piece, thereby isolating the guide, the guide sleeve and the connecting piece from the air, reducing the probability of rusting of the guide, the guide sleeve and the connecting piece, preventing the reliability of the guide, the guide sleeve and the connecting piece from being reduced due to rust, improving the reliability of the guide, the guide sleeve and the connecting piece, improving the reliability of the connection, and improving the reliability of the cement pole. A magnetic ring is arranged in the guide sleeve; the magnetic ring is arranged near one end of the bottom surface of the guide sleeve; the magnetic ring is fixedly connected with the guide sleeve. By setting the magnetic ring, when the end of the guide rod approaches the bottom surface of the guide sleeve, the outermost guide rod deforms outward under the action of the magnetic force of the magnetic ring, so that the guide rods are evenly distributed in the guide sleeve, increasing the gap between the ends of the guide rods, increasing the flow space of the slurry, increasing the fluidity of the slurry, improving the compactness of the slurry, increasing the strength after the slurry solidifies, increasing the connection strength of the pole body, increasing the overall strength of the cement pole, and improving the reliability of the cement pole. The inner hole of the guide sleeve is a tapered hole; the diameter of the inner hole of the guide sleeve gradually increases from the end face of the guide sleeve. By providing a tapered inner hole in the guide sleeve, the side face of the tapered inner hole limits the solidified slurry, thereby increasing the resistance to axial movement of the solidified slurry, increasing the resistance to mutual separation of the two pole bodies, increasing the tensile strength of the pole body, increasing the tensile strength of the cement pole, and improving the reliability of the cement pole.

[0034] The connecting piece is provided with a sealing layer on the outside. By setting the sealing layer (sealant or coating), after the two connecting pieces are welded and pass the inspection, the same sealing material is applied outside the weld, thereby covering the exposed connecting pieces and the weld, thereby isolating the connecting pieces and the weld from the air, thereby reducing the probability of rusting of the connecting pieces and the weld, thereby preventing the reliability of the connecting pieces and the weld from being reduced due to rust, thereby improving the reliability of the connecting pieces and the weld, thereby improving the reliability of the connection, and thereby improving the reliability of the cement pole. The connecting seat and the pole body are connected through a fixing seat; the fixing seat is cast together with the pole body; the connecting seat and the fixing seat are connected by threads. Through the threaded connection between the connecting seat and the fixing seat, the installation and removal of the guiding piece are facilitated. During the transportation of the pole body, the guiding piece is removed, and the guiding piece is transported separately from the pole body, thereby reducing the probability of damage to the guiding piece during transportation, thereby preventing the guiding effect of the guiding piece on the guiding sleeve from being reduced due to damage, thereby improving the centering quality between the guiding piece and the guiding sleeve, thereby improving the centering quality of the pole body, thereby improving the connection quality of the pole body, and thereby improving the reliability of the cement pole.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0037] Embodiment 1

[0038] Refer to Figures 1 - 7 As shown, this embodiment provides a cement pole, including a pole body 1. A top pole 4 is integrally cast at the top of the pole body 1. A cross arm 5 is installed on the top pole 4. Insulators are respectively arranged at both ends of the top surface of the cross arm 5 for winding electric wires. A bearing plate 3 is installed at a position near the top of the pole body 1. An opening 7 is provided on the bearing plate 3 for an operator to board or get off the bearing plate 3. A winding mechanism is installed on the top surface of the bearing plate 3, and a rope for transporting tools is wound on the winding mechanism.

[0039] During installation, use a crane to lift the rod body 1, keep the rod body 1 in the vertical direction, fix the bottom of the rod body 1, then install the bearing plate 3 on the rod body 1, and finally install the cross arm 5 on the top rod 4 in sequence. Then lay the electric wire on the insulator to complete the installation. During maintenance, the operator can board the bearing plate 3 through the opening 7. The operator only needs to tie the safety rope to the rod body 1. Standing on the bearing plate 3 to work is more convenient, and there is no need to climb with the whole body full of tools. The winding mechanism can be used to transport tools from the ground, reducing the load of the operator and improving work efficiency. The present invention is convenient for installation and has a good fixing effect on the cross arm 5. And the bearing plate 3 is provided to provide a working platform for the operator, and tools can also be transported, reducing the risk of the operator falling, and having higher work efficiency.

[0040] In a further optimized solution, the top rod 4 is in the shape of a cone that gradually thickens from top to bottom. The conical shape of the top rod 4 is convenient for the installation of the cross arm 5 and has better stability after installation.

[0041] In a further optimized solution, a central hole 8 is opened in the center of the cross arm 5. The central hole 8 passes through the top of the top rod 4. When the cross arm 5 moves down along the top rod 4 from top to bottom, the outer side of the top rod 4 gradually contacts and presses against the inner side of the central hole 8. Side holes 9 are symmetrically arranged on both sides of the central hole 8. When the angle of the cross arm 5 is adjusted, a wedge block is inserted into the side hole 9 for fixation.
