Description

Technical Field

[0001] The present application relates to the technical field of wind towers, and in particular to a guyed truss wind tower structure in coastal areas. Background Art

[0002] A wind tower is a tall tower structure specially designed for measuring wind energy parameters. It is mainly used to observe and record the movement of airflow near the ground. It is usually made of reinforced concrete or steel pipes. The wind tower continuously monitors the wind conditions of the wind farm around the clock by installing anemometers, wind vanes, and temperature and air pressure monitoring equipment at different heights, providing detailed and reliable data support for the assessment of wind energy resources. Wind towers are generally installed and used in flat and unobstructed locations on coastal hills. Wind towers are not only a bridge connecting nature and technology, but also an important basis for evaluating the potential of wind energy resources, project site selection and design decisions.

[0003] Because coastal areas are rich in wind energy resources year-round, wind towers are often constructed in coastal areas for wind measurement. However, due to the unique geological environment of coastal cities, which are often characterized by soft sand and gravel, coastal areas experience an average of over 200 days of windy conditions exceeding level 6 annually, and during typhoons, instantaneous wind speeds can reach level 13 or higher. This creates complex, fluctuating wind loads, causing the tower to tilt to a certain degree due to strong winds. This tilt increases the eccentricity of the gravity load, generating additional bending moments and increasing stress in the tower's main material. This stress concentration, particularly at the joints, can induce fatigue cracks in the steel and shorten the tower's service life. Furthermore, this tilt causes the sensor mounting plane to deviate from the horizontal reference, increasing the deviation of wind measurement data. Therefore, prolonged tower tilt can easily lead to tower deformation and metal fatigue. Consequently, due to metal damage and the tilting force of the foundation, the tower can further tilt or even collapse, causing economic and other losses and seriously impacting surrounding safety and the tower's stability.

[0051] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0052] Example 1

[0053] An embodiment of the present invention provides a guyed truss wind tower structure for coastal areas, comprising: a tower body 1, a base 2, a guyed seat 3, a concrete pier 4, and a steel bar hole 5. The tower body 1 is mounted on top of the base 2, which is made of reinforced concrete. The tower body 1 is 100-150 meters high, and the guyed seats 3 are arranged in a triangular shape around the base 2, with the distance between each two guyed seats 3 being 18-20 meters.

[0054] In this embodiment, reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 9 , both ends of the tower body 1 are fixedly connected with flanges, the tower bodies 1 are fixedly connected to each other by flanges and bolts, the top of the base 2 is fixedly connected to the tower column 22 by pre-buried reinforced concrete pouring, and the bottom of the tower body 1 is fixedly connected to the top of the tower column 22 by a flange. The tower body 1 is triangular in plan view, and a reinforcing truss is installed between every two columns of the tower body 1. A wire joint 23 is fixedly connected to the outside of the tower body 1, and the wire cable 6 is fixedly connected to the wire joint 23. There are four groups of steel bar holes 5, two groups of steel bar holes 5 penetrate the wire seat 3 horizontally, and the other two groups of steel bar holes 5 penetrate the wire seat 3 longitudinally, and then each group of steel bar holes 5 is opened on the side wall of the wire seat 3 in a longitudinal-transverse-longitudinal-transverse manner;

[0055] Based on the above structure and the connection relationship of the above structure, when constructing a wind measurement tower in a coastal area, a foundation pit is first dug at the construction site, and pile construction is carried out in the foundation pit. Then, steel bars are connected on the outside of the pile body by a hinged manner, and a tower column 22 is fixed on the top of the steel frame. Then, concrete is poured into the foundation pit. After the concrete solidifies and takes shape, the corresponding base 2 can be obtained. Then, the first section of the tower body 1 is fixed to the tower column 22 on the top of the base 2 by flanges and bolts. Then, the tower body 1 sections are stacked in sequence to the construction height by bolts and flanges, and a wind measurement platform is installed on the top layer of the tower body 1. The wind measurement platform is equipped with lightning rods, anemometers and other wind measurement tower related instruments. This is the application of the existing technology and will not be elaborated here. After completing the above installation and fixation, the wind measurement tower can be completed and put into use, wherein the wire seat 3 is constructed by the above construction method, and the steel bar hole 5 is used to insert the steel bar, and then concrete is poured to form a concrete pier 4 to fix the wire seat 3.

[0056] Furthermore, the wire pulling joint 23 is an extended metal plate, and a through hole is formed on the side of the metal plate near the bottom. A wire pulling cable 6 is wound and fixed in the through hole of the wire pulling joint 23. A pressure groove 8 and a tensioning groove 7 are respectively formed inside the wire pulling seat 3. The other end of the wire pulling cable 6 passes through and is slidably connected to the position of the wire pulling seat 3 near the top of the tensioning groove 7, wherein the two wire pulling cables 6 near the inside are fixedly connected to the inner groove wall at the bottom of the tensioning groove 7. A connecting hole 9 is formed on the inner wall of the wire pulling seat 3 near the pressure groove 8 and the bottom of the tensioning groove 7, and the connecting hole 9 is connected to the pressure groove 8 and the tensioning groove 7.

[0057] Furthermore, the bottom end of a pulling cable 6 of each pulling seat 3 away from the tower body 1 is fixedly connected to an extension cable 10, and the other end of the extension cable 10 is fixedly connected to a pressure plate 11, and the pressure plate 11 is adapted to and slidably connected to the inner groove of the pressure groove 8, and the position of the pressure groove 8 near the bottom of the pressure plate 11 is filled with liquid, and a sealing ring is provided at the interface position where the communicating hole 9 is connected to the pressure groove 8, and a movable hole 12 is opened through the inner wall of the pulling seat 3 between the pressure groove 8 and the tensioning groove 7, and a push rod 13 is slidably installed inside the movable hole 12, and a movable frame 14 is fixed to one end of the push rod 13 near the tensioning groove 7, and the movable frame 14 is U-shaped, and both ends of the top of the movable frame 14 are fixedly connected to movable rods 15, and a tensioning column 16 is fixedly connected between the two movable rods 15, and a locking block 17 is fixedly connected to the inner groove wall of the inner groove of the tensioning groove 7 relative to the movable rod 15;

[0058] The wire pulling roller 18 is rotatably connected to the inner groove wall position of the tensioning groove 7 near the bottom of the movable rod 15. The two ends of the wire pulling roller 18 are fixedly connected to the gear plate 19. The bottom of the movable rod 15 is fixedly connected to the meshing teeth 20. The movable rod 15 is meshed with the gear plate 19 through the meshing teeth 20. The contact detector 21 is installed at the top position of the movable rod 15.

[0059] Based on the above structure and the connection relationship of the above structure, when the wind measurement tower is in a windy state, due to its high height, it is necessary to fix the guy wire 6 to the guy wire joint 23 and the tensioning groove 7 of the guy wire seat 3 during construction. At this time, the guy wire 6 applies a pulling force to the tower body 1 from three directions, so that the tower body 1 can be perpendicular to the horizontal and ensure the stability of the tower body 1;

[0060] When it is windy, strong wind blows towards the tower body 1 from one side. When the wind is strong, the tower body 1 will tilt to a certain extent. When the tower body 1 tilts, the outermost guy cable 6 will drive the extension cable 10 to move in the connecting hole 9. At this time, the extension cable 10 drives the pressure plate 11 to move downward inside the pressure groove 8. At this time, the pressure plate 11 moves downward to squeeze the filled liquid into the movable hole 12. When the liquid enters the movable hole 12, the sealing disk 27 and the push rod 13 are pushed by the thrust of the liquid to move in the direction of the tightening groove 7. The push rod 13 moves in the direction of the tightening groove 7 and drives the movable frame 14 and the movable rod 15 to move in the direction of the guy cable 6. At this time, the guy cable 6 is squeezed and pushed by the tensioning column 16 to produce deformation, and the guy cable 6 is pulled into the tightening groove 7. Then the guy cable 6 can pull the tower body 1 to prevent the tower body 1 from tilting excessively due to strong winds, thereby ensuring the stability and safety of the wind measurement tower.

[0061] Furthermore, when the tensioning column 16 squeezes and pushes the pull cable 6 to cause deformation, the meshing teeth 20 at the bottom of the movable rod 15 drive the pull roller 18 to rotate through the gear plate 19, and then the pull roller 18 reels and tightens the corresponding pull cable 6, thereby providing a stronger pulling force for the corresponding pull cable 6, thereby ensuring that the stability and safety of the tower body 1 are further improved.

[0062] Here, the tensioning column 16 and the wire roller 18 are used to provide a tensioning force in the opposite direction of the wind to the wire cable 6, and at the same time provide a winding tension, so that the wire cable 6 can quickly and stably pull the tower body 1 of the wind measurement tower from an inclined state to a horizontal vertical state, so as to resist the load of strong winds, thereby preventing the tower body from tilting or bending for a long time due to strong winds, resulting in tower body bending deformation and metal fatigue, and also preventing excessive tilting from causing unilateral pressure settlement of the base 2, thereby ensuring the safety and stability of the wind measurement tower, thereby reducing damage to the wind measurement tower and improving its service life and safety.

[0063] Example 2

[0064] In this embodiment, reference Figure 7 、 Figure 8 and Figure 10 , a locking groove 28 is provided on the side of the locking block 17 relative to the movable rod 15, and an insertion slope 31 is provided on the end of the movable rod 15 away from the movable frame 14, and the end of the movable rod 15 is adapted to be plugged into the locking groove 28;

[0065] Furthermore, the locking block 17 is provided with an inner groove 32 at a relative position of the upper and lower inner groove walls near the locking groove 28, and the inner groove 32 is adapted to be slidably connected with a limit plate 33. A second spring 34 is fixedly connected between the side of the limit plate 33 near the inner groove 32 and the inner groove wall opposite thereto. A clamping strip 29 is fixedly connected to the opposite side of the two limit plates 33. The clamping strip 29 is adapted to and slidably connected to the opening of the inner groove 32. A plurality of clamping slots 30 are provided on the upper and lower outer walls of the movable rod 15 near one end of the insertion slope 31, and the clamping strip 29 is adapted to be plugged into the clamping slot 30.

[0066] Furthermore, a pull rope 35 is fixedly connected to one side of the limit plate 33 near the inner groove of the inner receiving groove 32, a winding groove 36 is opened inside the locking block 17, and a winding disk 37 is rotatably installed inside the winding groove 36. The pull rope 35 passes through the inner wall of the locking block 17 and is fixed and wound on the winding disk 37. A servo motor 38 is installed on the internal bolts of the side of the locking block 17 near the winding groove 36. The servo motor 38 is externally connected to an electric wire, which passes through the locking block 17 and the wire pull seat 3 and is electrically connected to the external power supply equipment. This is an application of the existing technology and will not be elaborated here. The output end of the servo motor 38 passes through the inner wall of the locking block 17 and is fixedly connected to the opposite side of the winding disk 37.

[0067] When the locking plate 33 is in the locking groove 32, the clamping strip 29 is aligned with the clamping groove 30, and the second spring 34 is not squeezed and can rebound, pushing the limiting plate 33 and the clamping strip 29 to move to the outside of the inner groove 32. At this time, the clamping strip 29 can be inserted into the clamping groove 30, completing the fixation of the movable rod 15, thereby ensuring that the tensioning column 16 can continuously and stably pull the pull cable 6, so that it can provide wind-resistant pulling force for the tower body 1, thereby preventing the tower body 1 from tilting and being damaged due to strong winds.

[0068] When the wind measuring instrument on the top of the tower body 1 detects that there is no strong wind in the surrounding environment, the servo motor 38 starts, driving the reel 37 to rotate, and the reel 37 reels the pull rope 35. The pull rope 35 can drive the limit plate 33 and the card strip 29 to move into the inner groove 32, and the card strip 29 moves out of the card slot 30, releasing the limit on the movable rod 15, and then the movable rod 15 can be reset, and the pull cable 6 can be released from the force and reset.

[0069] Example 3

[0070] In this embodiment, reference Figure 5 and Figure 6 A detection seat 39 is fixedly connected to the top of the movable rod 15. The bottom of the inner groove of the detection seat 39 is an inclined surface facing the locking block 17. A trigger contact 41 is installed on the inclined surface. A trigger plate 40 is rotatably connected to the inner side of the detection seat 39 near the position above the trigger contact 41. A rebound torsion spring 42 is provided at the rotating shaft position of the trigger plate 40 and the detection seat 39. The top edge of the trigger plate 40 facing the locking block 17 is chamfered.

[0071] Based on the above structure and the connection relationship of the above structure, when the tensioning column 16 moves in the direction of the pulling cable 6, the tensioning column 16 squeezes the pulling cable 6 and rotates at the same time. Then the tensioning column 16 squeezes the pulling cable 6 to present a state where the wire is pointed, and the pulling roller 18 also reels and tightens the pulling cable 6 at the same time. At this time, the upper part of the pulling cable 6 will press down the trigger plate 40, causing it to rotate inside the detection seat 39 and causing the rebound torsion spring 42 to shrink and tighten. At the same time, the trigger plate 40 contacts the trigger contact 41. At this time, the movable rod 15 and the locking block 17 are in a locked state. The trigger contact 41 is triggered to confirm the locked state. The trigger contact 41 is electrically connected to the servo motor 38 through wires. The wire is a commonly used flexible wire, and its length needs to be greater than the distance between the trigger contact 41 and the servo motor 38 in the reset state. It is an application of the existing technology and will not be elaborated here. When the strong wind ends or the wind direction blows back, the pull cable 6 will become loose to a certain extent from the taut state because it is not affected by the wind force or is affected by the reverse wind force. At this time, the pull cable 6 does not press down the trigger plate 40, and the trigger plate 40 rebounds through the rebound torsion spring 42. The rebound rotation distance of 0.5 cm can trigger the unlocking instruction of the trigger contact 41, and then the instruction is sent to the servo motor 38, and then the servo motor 38 executes the command, automatically releasing the limit of the locking block 17 on the movable rod 15, and then each structure is reset, and the wind measurement tower continues to be used.

[0072] Example 4

[0073] In this embodiment, reference Figure 5 、 Figure 9 and Figure 10 A sliding rod 25 is fixedly connected between the inner groove walls on both sides of the tensioning groove 7 near the upper side of the movable rod 15. The sliding rod 25 is parallel to the movable rod 15. Two sliders 24 are sleeved and slidably connected to the outer side of the sliding rod 25. The two sliders 24 are fixedly connected to the top of the movable rod 15. A No. 1 spring 26 is fixedly connected between the slider 24 near the locking block 17 and the inner groove wall opposite to the tensioning groove 7.

[0074] Based on the above structure and the connection relationship of the above structure, when the movable rod 15 is pushed by the push rod 13 and the movable frame 14, the movable rod 15 moves in the tensioning groove 7. During the process, the movable rod 15 slides on the slide rod 25 through the slider 24 to ensure its stability, and will squeeze the No. 1 spring 26 to contract. Then the movable rod 15 is fixed by the locking block 17. When the locking block 17 is released from the limit, the No. 1 spring 26 can rebound, pushing the movable rod 15, the movable frame 14 and the push rod 13 to move in the opposite direction and reset. At the same time, the liquid in the movable hole 12 is also squeezed into the pressure groove 8. At this time, the pressure plate 11 will reset upward because the liquid fills the pressure groove 8. The pressure plate 11 then pulls the extension cable 10 and the pull cable 6 to reset.

[0075] Furthermore, the diameters of both ends of the movable hole 12 are smaller than the diameter of the middle section. The end of the push rod 13 close to the pressure groove 8 is fixedly connected to a sealing disk 27. The sealing disk 27 is adapted to and slidably connected to the inner groove of the middle section of the movable hole 12.

[0076] Furthermore, a marking limit rod 43 is fixedly connected to the top of the pressure plate 11 , a scale is provided on the surface of the marking limit rod 43 , and the marking limit rod 43 passes through the top of the base 2 and is slidably connected.

[0077] Based on the above structure and the connection relationship of the above structure, the marking limit rod 43 moves downward with the pressure plate 11, which is convenient for manual inspection in windy weather. According to the up and down movable positions of multiple groups of marking limit rods 43, it is convenient to confirm the tilt of the wind measurement tower caused by the wind, which is convenient for subsequent manual maintenance and inspection. The status of the downward pressure distance of the movable rod 15 by the pressure plate 11 is convenient for judging the tensioning force of the movable rod 15 and the tensioning column 16 on the tension cable 6 in this strong wind, which is convenient for subsequent inspection and calibration.

[0078] The working process of the present invention is as follows: when constructing a wind measurement tower in a coastal area, a foundation pit is first dug at the construction site, and then the base 2 and the tower column 22 are constructed. Then, several wire-drawing seats 3 are set at equal intervals, and a foundation pit is dug around the base 2. The wire-drawing seat 3 is then inserted into the steel bar hole 5 and placed in the corresponding foundation pit to build a concrete pier 4. Then, wait for the concrete to be poured and fixed. The fixed installation of the base 2 and the wire-drawing seat 3 is completed. Then, the tower body 1 is fixed to the tower column 22 on the top of the base 2 through flanges and bolts. Then, the tower body 1 is stacked in sequence to the construction height through bolts and flanges. When strong winds occur, strong winds blow towards the tower body 1 from one side. When the wind is strong, the tower body 1 will tilt to a certain extent. When the tower body 1 tilts, the wire-drawing seat 3 away from the outer side of the tower body 1 will drive the extension cable 10 to move in the connecting hole 9. At this time, the extension cable 10 drives the pressure The disk 11 moves downward inside the pressure groove 8. At this time, the pressure plate 11 moves downward to squeeze the filled liquid into the movable hole 12. The push rod 13 and the sealing disk 27 are pushed by the liquid, and the push rod 13 moves in the direction of the tensioning groove 7 and drives the movable frame 14 and the movable rod 15 to move in the direction of the guy cable 6. At this time, the guy cable 6 is squeezed and pushed by the tensioning column 16 to produce deformation, and the guy cable 6 is pulled into the tensioning groove 7, and then the guy cable 6 can pull the tower body 1 to prevent the tower body 1 from tilting excessively due to strong winds, thereby ensuring the stability and safety of the wind measurement tower. At the same time, when the tensioning column 16 squeezes and pushes the guy cable 6 to produce deformation, the meshing teeth 20 at the bottom of the movable rod 15 drive the guy wire roller 18 to rotate through the gear disk 19, and then the guy wire roller 18 reels and tightens the corresponding guy wire 6, thereby providing a stronger pulling force for the corresponding guy wire 6, thereby improving the wind resistance of the wind measurement tower and making the wind measurement tower have stronger stability.
