Description

Technical Field

[0001] This invention belongs to the field of power transmission tower reinforcement and maintenance, and relates to a power transmission tower straightening and reinforcement device and its construction method. Background Technology

[0002] Transmission towers are the core supporting facilities of power transmission systems. Exposed to complex outdoor environments for extended periods, they are susceptible to uneven settlement of the tower foundation due to factors such as geological subsidence, wind and rain loads, and environmental temperature differences. This can lead to tower tilting and displacement. The tilting deviation of the tower directly alters the tension parameters of the transmission line, causing problems such as abnormal line sag and substandard spacing. This significantly increases the probability of power line malfunctions and threatens the safe and stable operation of the regional power grid.

[0003] Currently, the industry primarily employs a method of overall jacking and calibration followed by external steel frame reinforcement for straightening and reinforcing tilted transmission towers. However, existing straightening equipment suffers from poor fit between the support structure and the tower's load-bearing structure during operation, making it difficult to achieve multi-angle, high-precision fine-tuning and calibration, and thus unable to meet the precise correction requirements for slight tower tilt. Furthermore, existing reinforcement connection structures are mostly rigid butt joints; when foundation settlement or tower deformation and displacement occur, stress concentration easily occurs at the connection points, leading to problems such as bolt breakage and connection failure, failing to continuously guarantee the tower's connection stability.

[0004] In addition, the existing equipment's support and positioning structure has limited adaptability, and the support base's fit and fixation to the ground are insufficient during operation, making it difficult to guarantee operational stability. The connection and fastening structure is exposed to the outdoor environment for extended periods, easily accumulating debris and coming into contact with rainwater. Long-term erosion will affect the fastening performance of the connection structure, shorten the effective service life of the equipment, and fail to meet the long-term, stable straightening, reinforcement, and maintenance needs of transmission towers. Summary of the Invention

[0005] In view of this, in order to solve the problems of poor stress adaptability, low calibration accuracy and insufficient protection performance of existing tower straightening structures, the present invention provides a power transmission tower straightening and reinforcement device and its construction method.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A transmission tower straightening and reinforcement device includes a tower body and four pre-embedded bases, and further includes: four support plates fixedly installed at the four corners of the bottom of the tower body; each of the four pre-embedded bases has a pre-embedded groove on its top, and a pre-embedded sleeve is fixedly embedded inside the pre-embedded groove; multiple circular holes I are opened inside the support plates, and connecting components for connecting the pre-embedded sleeves and support plates are provided inside the circular holes I; a protective component for protecting the connecting components is provided on the top of the support plates; a U-shaped frame is fixedly installed inside the tower body, and a cross-shaped reinforcing plate is fixedly installed inside the U-shaped frame; and a support base is also included, located below the cross-shaped reinforcing plate; four fixing rods are fixedly installed on the top of the support base; the same flat plate is fixedly installed on the top of the four fixing rods; a straightening component for straightening the tower body is provided on the top of the flat plate; and a stabilizing component for stabilizing the device is provided inside the support base.

[0008] Furthermore, the connecting assembly includes a rigid outer cylinder fixedly embedded inside the circular hole I. The internal thread of the pre-embedded sleeve is through which a mounting bolt passes. The same rubber ring is provided between the thread head of the mounting bolt and the top of the pre-embedded sleeve and the two ends of the rigid outer cylinder, respectively. A copper annular block is fixedly installed on the inner wall of the rigid outer cylinder. Multiple connecting blocks are fixedly installed on the inner wall of the rigid outer cylinder. The same support ring is fixedly installed at one end of the multiple connecting blocks. The inner wall of the support ring abuts against the mounting bolt. The top and bottom of the connecting blocks are provided with inclined grooves.

[0009] Furthermore, the protective component includes a protective shell, an mounting protrusion fixedly installed on the outer wall of the protective shell, multiple mounting holes opened inside the mounting protrusion, multiple drain ports opened on the inner wall of the protective shell, multiple clearance grooves opened on the top of the support plate, a drain rack fixedly connected to one end of the drain port, one end of the drain rack penetrating through the protective shell, and a rotating baffle hinged to the top inner wall of the end of the drain rack away from the protective shell.

[0010] Furthermore, the straightening component includes a circular hole II inside the flat plate, a main push rod is slidably connected inside the circular hole II, a spherical hinge I is fixedly installed on the piston rod of the main push rod, a support top plate is fixedly installed on the top of the spherical hinge I, a lower pressure plate is fixedly installed on the bottom of the main push rod, and multiple compression springs are provided between the bottom of the lower pressure plate and the top of the support base.

[0011] Furthermore, the support top plate has multiple strip-shaped holes inside, and sliding grooves are provided on both sides of the inner wall of the strip-shaped holes. Sliding blocks are slidably connected inside the sliding grooves. The same support horizontal plate is fixedly installed between the multiple sliding blocks. A fine-tuning plate is fixedly installed on the top of the support horizontal plate. A secondary push rod is fixedly installed on the top of the flat plate. A spherical hinge II is fixedly installed on the top of the secondary push rod. The top of the spherical hinge II is fixedly connected to the bottom of the support horizontal plate.

[0012] Furthermore, rectangular holes are provided around the bottom of the pressure plate, and the rectangular holes slide with the fixing rod. Arc-shaped surfaces are provided around the bottom of the pressure plate.

[0013] Furthermore, the stabilizing component includes multiple mounting notches on the periphery of the support base, with the same rotating shaft rotatably connected between the inner walls of the two sides of the mounting notches. A rotating push plate is fixedly fitted on the outer wall of the rotating shaft, and clearance openings are provided on both sides of the rotating push plate. It also includes a torsion spring, which is fitted on the outer wall of the rotating shaft. The two ends of the torsion spring are respectively fixed to the inner wall of one side of the clearance opening and the inner wall of one side of the mounting notch. A spherical pressing block is fixedly installed on one side of the bottom of the rotating push plate, and the arc-shaped surface cooperates with the rotating push plate.

[0014] Furthermore, a sliding plate adapted to the spherical pressing block is slidably installed inside the installation notch, and longitudinal blocks are fixedly installed on both sides of the inner wall of the installation notch. Longitudinal holes adapted to the longitudinal blocks are opened on both sides of the sliding plate.

[0015] Furthermore, multiple fixed tips are fixedly installed on the bottom of the sliding plate.

[0016] A method for straightening and reinforcing power transmission towers includes the following steps:

[0017] S1. Move the fully assembled support base to a position directly below the tower body to be corrected, so that the straightening component above the support base is directly opposite the bottom area of ​​the cross reinforcement plate.

[0018] S2. Start the main push rod to lift upwards. The main push rod drives the support top plate to fit against the bottom of the cross reinforcement plate through the ball joint I. While the main push rod is under force, it drives the lower pressure plate to slide down along the fixed rod and squeeze the compression spring. The arc surface at the bottom of the lower pressure plate continues to squeeze the rotating push plate, causing the rotating push plate to rotate around the rotating axis and twist the torsion spring. The rotating push plate drives the ball pressing block to press down the sliding plate. The sliding plate moves vertically down along the longitudinal block through the longitudinal hole, causing the bottom fixed tip to penetrate into the ground soil to complete the positioning and fixing of the support base.

[0019] S3. Based on the tilt deviation of the tower body, activate multiple sets of auxiliary push rods. The auxiliary push rods drive the support horizontal plate and the fine adjustment plate to finely adjust the lifting and lowering through the ball joint II. The sliding block slides along the sliding groove to adapt to the position deviation, and works with the main push rod to complete the angle leveling of the cross reinforcement plate and the tower body.

[0020] S4. After the tower body is leveled, remove the original installation bolts between the support plate and the pre-embedded sleeve, replace them with new installation bolts to complete the fastening assembly, and fix the protective shell to the top of the support plate through the installation protrusion plate. Rainwater and impurities generated during the operation can be discharged to the outside through the drain outlet and drain rack.

[0021] S5. After the operation is completed, control the main push rod and the auxiliary push rod to reset, the torsion spring drives the rotating push plate to reset, release the pressing constraint on the sliding plate, and lift the support base to complete the whole set of straightening and reinforcement operations.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The transmission tower straightening and reinforcement device disclosed in this invention sets support plates at the four corners of the tower bottom, which, together with the pre-embedded sleeves inside the pre-embedded base and the connecting components, complete the fixed connection, achieving uniform reinforcement of the tower bottom at multiple points. The rigid outer cylinder, rubber ring, and copper annular block form a multi-level buffer protection structure. When the foundation sinks slightly and the tower body shifts slightly, the rubber ring can offset the small displacement stress by using its own deformation to buffer the friction generated by the shaking structure. When the foundation sinks significantly and the tower body shifts a large amount, the connecting block can break along the inclined groove, releasing the rigid limit and allowing the mounting bolts to contact the copper annular block. The deformation of the copper annular block adapts to the tilt angle of the tower body, effectively dispersing the structural stress and preventing the mounting bolts from breaking due to stress concentration, thus continuously ensuring the reliability of the connection between the tower body and the pre-embedded base.

[0024] 2. The transmission tower straightening and reinforcement device disclosed in this invention features an independent support base as the straightening operation platform. The stabilizing components inside the support base can be autonomously fixed during the straightening operation. During the downward pressing of the main push rod, the arc-shaped surface of the lower pressure plate presses against the rotating push plate, causing the rotating push plate to deflect and drive the sliding plate to move longitudinally downwards along the longitudinal block, allowing the fixing tip to insert into the soil. Relying on the soil's limiting effect, the support base is fixed at a specific point, improving the overall stability of the equipment during the straightening operation and providing a stable force foundation for tower straightening and calibration. A torsion spring can drive the rotating push plate to reset after the operation is completed, facilitating the repeated use of the equipment.

[0025] 3. The transmission tower straightening and reinforcement device disclosed in this invention adopts a two-stage straightening and adjustment structure with a main push rod and multiple sets of auxiliary push rods. The main push rod can realize the overall lifting and leveling of the cross reinforcement plate, and the auxiliary push rods can complete the local angle fine adjustment through the support horizontal plate and the fine adjustment plate. Combined with the universal angle adaptation characteristics of spherical hinge I and spherical hinge II, it can accurately correct the multi-angle tilt deviation of the tower body, improve the accuracy of tower straightening and calibration, and ensure that the verticality of the tower installation meets the operation and maintenance standards.

[0026] 4. The transmission tower straightening and reinforcement device disclosed in this invention features a protective component on the top of the support plate. The protective shell provides all-around protection for the internal mounting bolts, rigid outer cylinder, and other connecting structures. External rainwater, dust, and other impurities can be quickly discharged through the drain port and drain rack on the inner wall of the protective shell. A rotating baffle can block the drain rack port when there is no draining operation, reducing the entry of debris into the protective shell, effectively maintaining the working condition of the connecting components, extending the overall service life of the device, and reducing the frequency of later tower maintenance.

[0027] 5. The transmission tower straightening and reinforcement device disclosed in this invention enhances the structural strength of the tower body through the internal spiral frame and cross reinforcing plate. Combined with the bottom multi-point reinforcement structure and precise straightening structure, it realizes the integrated operation of tower structure reinforcement and tilt correction. The operation process has strong connectivity and can effectively improve the overall quality of transmission tower operation and maintenance, and ensure the stable operation of power grid transmission.

[0042] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0043] like Figure 1 The power transmission tower shown includes a tower body 1 and four pre-embedded bases 3. Four bases 3 are fixedly installed at the four corners of the bottom of the tower body 1. Figure 4 The support plate 10 shown has four embedded bases 3, each with an embedded groove 12 at its top. An embedded sleeve 11 is fixedly embedded inside the embedded groove 12. The support plate 10 has multiple circular holes I 14 inside, each containing a connecting assembly. These connecting assemblies are used to securely connect the embedded sleeve 11 and the support plate 10. A protective assembly is mounted on the top of the support plate 10 to protect and shield the connecting assembly. The internal fixed installation at the bottom of the tower body 1 is as follows... Figure 2 The spiral frame 5 shown has a cross-shaped reinforcing plate 2 fixedly installed inside it. The spiral frame 5 and the cross-shaped reinforcing plate 2 work together to effectively improve the overall structural strength of the tower body 1 and enhance the load-bearing capacity and structural stability of the tower body 1.

[0044] like Figure 8As shown, the transmission tower straightening and reinforcement device also includes a support base 4, which is located directly below the cross-shaped reinforcing plate 2. The top of the support base 4 is fixedly installed as shown in the figure. Figure 10 The four fixed rods 41 shown are all fixedly mounted on the same flat plate 42 at their tops. The top of the flat plate 42 is equipped with a straightening component, which is used to perform angle calibration and leveling operations on the tilted tower body 1. The support base 4 is equipped with a stabilizing component inside, which can complete the ground fixation of the support base 4 during the straightening operation, ensuring the overall stability of the equipment during the operation.

[0045] Specifically, such as Figure 5 The connecting assembly shown includes a rigid outer cylinder 19 fixedly embedded inside the circular hole I 14. An internal threaded mounting bolt 17 is fitted onto the pre-embedded sleeve 11. The lower part of the threaded head of the mounting bolt 17 and the top of the pre-embedded sleeve 11 are respectively fitted with the same type of mounting bolt between them and both ends of the rigid outer cylinder 19. Figure 6 The rubber ring 18 shown is fixedly installed on the inner wall of the rigid outer cylinder 19 as follows: Figure 7 The copper annular block 20 shown has multiple connecting blocks 21 fixedly installed on the inner wall of the rigid outer cylinder 19. One end of each connecting block 21 is fixedly fitted with the same support ring 23. The inner wall of the support ring 23 abuts against the outer wall of the mounting bolt 17. Sloping grooves 22 are provided at the top and bottom of the connecting blocks 21. Therefore, during actual use, if a slight subsidence of the foundation causes a small tilting or swaying of the tower body 1, the rubber rings 18 arranged on the upper and lower sides of the support plate 10 can fill the structural gaps. Through their own deformation, they buffer the frictional stress generated by the structural swaying, offsetting the structural tension caused by the small displacement and preventing hard wear on the components.

[0046] Based on this, when the foundation experiences significant subsidence and the tower body 1 tilts and shifts dramatically, the support ring 23 inside the rigid outer cylinder 19 will continuously contact the mounting bolt 17 and bear compressive stress. The structure of the inclined groove 22 can reduce the structural strength of the connecting block 21, causing the connecting block 21 to break under overload stress, thus releasing the rigid constraint of the support ring 23 on the mounting bolt 17. Preferably, the inner diameter of the copper annular block 20 is smaller than the inner diameter of the support ring 23. After the connecting block 21 breaks, the mounting bolt 17 no longer contacts the support ring 23, but instead contacts the copper annular block 20. Relying on the metal deformation properties of the copper annular block 20 to adapt to the tilt angle of the support plate 10, the overall structural stress is dispersed, preventing the mounting bolt 17 from breaking due to stress concentration, and continuously ensuring the connection stability between the tower body 1 and the embedded base 3.

[0047] Specifically, such as Figure 3 , 4As shown, the protective assembly includes a protective shell 6. A mounting protrusion 15 is fixedly installed on the outer wall of the protective shell 6. Multiple mounting holes 8 are formed inside the mounting protrusion 15. The protective shell 6 can be detachably fixed to the top of the support plate 10 through the mounting holes 8 and fasteners. Multiple drain ports 16 are formed on the inner wall of the protective shell 6. Multiple clearance grooves 13 are formed on the top of the support plate 10. The clearance grooves 13 can adapt to the assembly dimensions of the protective shell 6, avoiding structural interference. One end of the drain port 16 is fixedly connected to an interconnected drain rack 7. One end of the drain rack 7 extends through to the outside of the protective shell 6. A rotating baffle 9 is hinged to the inner wall of the top of the end of the drain rack 7 away from the protective shell 6. Based on this, the protective shell 6 can provide all-round protection for the core connecting components such as the internal mounting bolts 17 and rigid outer cylinder 19, preventing the accumulation of external debris. External rainwater can flow into the drain rack 7 through the drain port 16 and be quickly discharged into the protective shell 6. In the absence of rainwater drainage, the rotating baffle 9 can rely on its own weight to fit against the port of the drain rack 7, blocking external dust and debris from entering the protective shell 6, continuously maintaining the working environment of the connecting components, and extending the service life of the components.

[0048] Furthermore, such as Figure 10 As shown, the straightening assembly includes a circular hole II 34 opened inside the flat plate 42. A main push rod 33 is slidably connected inside the circular hole II 34. A spherical hinge I 25 is fixedly installed at the piston rod end of the main push rod 33. A support top plate 24 is fixedly installed at the top of the spherical hinge I 25. A lower pressure plate 35 is fixedly installed at the bottom of the main push rod 33. Multiple compression springs 38 are assembled between the bottom of the lower pressure plate 35 and the top of the support base 4. During operation, the support base 4 is moved directly below the tower body 1, and the main push rod 33 is activated. The piston rod of the main push rod 33 extends upward, driving the support top plate 24 to gradually rise and fit against the bottom of the cross reinforcing plate 2. During the continuous lifting process, the initial straightening support of the tower body 1 is completed. When the main push rod 33 is under working force, it will apply downward pressure to the bottom pressure plate 35. The pressure plate 35 simultaneously squeezes multiple compression springs 38. The compression springs 38 contract under force, which can buffer the downward pressure force and balance the overall force of the equipment. A controller is fixedly installed on the side of the flat plate 42. The controller is electrically connected to the main push rod 33 and multiple sets of auxiliary push rods 32. The operator can adjust the extension and retraction stroke of each push rod through the controller to complete the precise calibration of the tilt angle of the tower body 1.

[0049] Specifically, such as Figure 9As shown, the four corners of the support top plate 24 are provided with strip holes 30. The inner walls of both sides of the strip holes 30 are provided with sliding grooves 29. Sliding blocks 26 are slidably connected inside the sliding grooves 29. The same support horizontal plate 28 is fixedly installed among multiple sliding blocks 26. A fine adjustment plate 27 is fixedly installed on the top of the support horizontal plate 28. A secondary push rod 32 is fixedly installed on the top of the flat plate 42. A spherical hinge II 31 is fixedly installed on the top of the secondary push rod 32. The top of the spherical hinge II 31 is fixedly connected to the bottom of the support horizontal plate 28. After the main push rod 33 completes the initial lifting support, multiple sets of auxiliary push rods 32 arranged around the perimeter can work together. The extension and retraction of the auxiliary push rods 32 drive the support plate 28 to rise and fall. The sliding block 26 slides smoothly along the sliding groove 29 to ensure the stability of the movement of the support plate 28. The fine-tuning plate 27 moves synchronously with the support plate 28 and makes fine-tuning support by fitting the bottom part of the cross reinforcing plate 2. With the universal angle adaptation performance of the spherical hinge I 25 and the spherical hinge II 31, the tilt angle between the cross reinforcing plate 2 and the tower body 1 is accurately corrected, and the overall leveling operation of the tower body 1 is gradually completed.

[0050] Furthermore, rectangular holes 36 are provided around the bottom of the pressure plate 35. The rectangular holes 36 and the fixing rod 41 form a sliding fit structure. The pressure plate 35 can slide vertically along the direction of the fixing rod 41, which limits the movement trajectory of the pressure plate 35 and avoids positional deviation during operation. The bottom of the pressure plate 35 is provided with arc-shaped surfaces 37 around the bottom. The arc-shaped surfaces 37 can realize the smooth transmission of force and the smooth contact of the structure.

[0051] Specifically, such as Figure 11 As shown, the stabilizing component includes multiple mounting notches 45 formed around the periphery of the support base 4. A common rotating shaft 47 is rotatably connected between the inner walls of both sides of the mounting notches 45. A rotating push plate 43 is fixedly fitted onto the outer wall of the rotating shaft 47. Both sides of the rotating push plate 43 have clearance openings 44. A torsion spring 46 is fitted onto the outer wall of the rotating shaft 47, with its two ends fixed to one inner wall of the clearance opening 44 and one inner wall of the mounting notch 45, respectively. A spherical pressing block 50 is fixedly installed on one side of the bottom of the rotating push plate 43. The arc-shaped surface 37 at the bottom of the lower pressure plate 35 forms a mating structure with the rotating push plate 43. During the downward movement of the main push rod 33, which drives the lower pressure plate 35 downward, the arc-shaped surface 37 gradually contacts and presses against the top of the rotating push plate 43, causing the rotating push plate 43 to deflect around the rotating shaft 47. The torsion spring 46 is subjected to force and undergoes torsional deformation. Simultaneously, the deflection of the rotating push plate 43 causes the spherical pressing block 50 at the bottom to move downward.

[0052] Furthermore, longitudinal blocks 49 are fixedly installed on both inner walls of the mounting notch 45. The device is also equipped with a sliding plate 40, with longitudinal holes 48 on both sides of the sliding plate 40. The longitudinal holes 48 and the longitudinal blocks 49 form a sliding guide fit. Multiple fixed tips 39 are fixedly installed on the bottom of the sliding plate 40. Preferably, the fixed tips 39 are made of high-strength alloy material, which has excellent structural strength and wear resistance, and can be stably inserted into the soil. A limit block is fixedly installed at the bottom of the longitudinal block 49. The limit block is used to limit the downward stroke of the sliding plate 40 and drive the sliding plate 40 to move upward and reset. After the spherical pressing block 50 moves down, it will abut against and push the sliding plate 40. The sliding plate 40 maintains a vertical downward movement state through the guiding and limiting effect of the longitudinal holes 48 and the longitudinal blocks 49, which drives the multiple fixed tips 39 at the bottom to move down synchronously and insert into the ground soil. Through the limiting effect of the soil on the fixed tips 39, the support base 4 is fixed as a whole, preventing the support base 4 from slipping or shifting during the straightening operation, and ensuring the stability of the straightening operation.

[0053] Based on this, after completing the overall leveling of tower body 1, the old mounting bolts 17 between tower body 1 and the pre-embedded base 3 can be removed and replaced with new mounting bolts 17 to re-tighten and connect, further improving the connection tightness at the bottom of tower body 1 and ensuring the structural stability of the reinforced tower body 1 during long-term operation. After the operation is completed, the main push rod 33 resets to release the downward pressure force, the torsion spring 46 releases the deformation elastic force, and drives the rotating push plate 43 to rotate in the opposite direction to reset, releasing the pressing limit on the sliding plate 40. The fixed tip 39 can then be directly pulled out of the soil, completing the disassembly and storage of the equipment, facilitating its repeated reuse. Preferably, the rotating push plate 43 is made of carbon steel, which has high structural rigidity and can withstand repeated compression and torsional forces, making it less prone to deformation and damage during long-term operation.

[0054] When the transmission tower straightening and reinforcement device is in use, the support base 4 can be moved as a whole to the bottom of the tower body 1. At this time, the main push rod 33 can be activated. The piston rod of the main push rod 33 drives the support top plate 24 to rise. When the main push rod 33 contacts the bottom of the cross reinforcing plate 2, it can provide downward pressure to the lower pressure plate 35 below. At this time, the lower pressure plate 35 squeezes multiple compression springs 38 and abuts against multiple external rotating push plates 43 through the arc surface 37. At this time, the rotating push plate 43 rotates around the rotating shaft 47, the torsion spring 46 is twisted, the rotating push plate 43 drives the spherical pressing block 50 to move down, the spherical pressing block 50 pushes the sliding plate 40 to move down, the sliding plate 40 moves down gradually through the longitudinal hole 48 and the longitudinal block 49, the sliding plate 40 drives multiple fixed tips 39 to move down and insert into the soil, which can ensure the stability of the device; the angle of the cross reinforcing plate 2 is continuously adjusted by the main push rod 33 and the auxiliary push rods 32 around it, which helps the cross reinforcing plate 2 and the tower body 1 to gradually level up, and the auxiliary push rods 32 can drive the supporting horizontal plate 28 and the fine adjustment plate 27 to move up, thereby driving the cross reinforcing plate 2 to make fine adjustments. After leveling, the original bolts can be removed and new mounting bolts 17 can be replaced to improve the stability of the device.

[0055] When foundation subsidence occurs, the device tilts slightly. At this time, the support plate 10, properly filled with rubber rings 18 at both ends, can be cushioned by friction during slight swaying. However, in the event of significant subsidence, the support ring 23 inside the rigid outer cylinder 19 will contact the mounting bolt 17. The inclined groove 22 can cause the connecting block 21 to break. Since the inner diameter of the copper annular block 20 is smaller than the inner diameter of the support ring 23, the mounting bolt 17 will only contact the copper annular block 20 after the connecting block 21 breaks. The deformation of the copper annular block 20 then adapts to the support plate. The tilt of 10 will not directly cause the installation bolt 17 to break, and the top of the pre-embedded seat 3 is detachably connected to the protective shell 6. The protective shell 6 can protect multiple installation bolts 17. Rainwater and other impurities will be discharged through the drain port 16 and the drain rack 7, extending the service life of the device. After each outdoor operation, it is necessary to clean the sand and dirt from the moving parts such as the sliding groove 29, longitudinal block 49, and rotating shaft 47 in a timely manner, and apply grease regularly to ensure smooth operation.
