A wind turbine foundation surveying device

Abstract

This invention discloses a wind turbine foundation surveying device, including a drilling machine and a drill rod, a multi-link moving mechanism, and an open ring frame. The multi-link moving mechanism is rotatably connected to the drilling machine, and the open ring frame is rotatably mounted on the multi-link moving mechanism to allow the ring frame to be fitted onto the drill rod through the opening. Simultaneously, an arc-shaped frame is provided on the ring frame. Driven by a motor, the arc-shaped frame rotates on the ring frame, causing a notched ring gear to drive it to rotate. This allows a rotating striking mechanism on the arc-shaped frame to strike the drill rod to extract samples from inside. Furthermore, a transverse striking mechanism is provided to strike the drill rod at different positions along its axial direction, effectively improving the sampling efficiency of soil and rock samples from inside the drill rod and significantly reducing the labor required for manual sampling in wind turbine foundation surveying.

Description

Technical Field

[0001] This invention relates to the field of drilling technology, and more specifically to a wind turbine foundation surveying device. Background Technology

[0002] In recent years, countries have increasingly emphasized the issue of air pollution. Traditional fossil fuels generate large amounts of waste gas during use, causing air pollution. New, pollution-free, renewable green energy sources have seen rapid development. Compared to traditional thermal power generation, wind power does not emit greenhouse gases during operation, causing no pollution to the environment, making it a new type of renewable energy. The energy generated by a wind turbine over a typical operating period of 20 to 50 years is approximately 80 times its consumption. Therefore, compared to traditional power generation methods, wind power has a high cost-performance ratio. In recent years, wind power has experienced rapid development globally, with many countries strongly supporting the development of clean and sustainable energy. As wind power technology improves, leveraging relatively superior wind energy resources, favorable site conditions, and relatively low foundation costs, wind power is accounting for an increasingly larger proportion of all power generation methods.

[0003] The development of wind power generation in my country can be divided into two stages: first, the introduction of advanced technologies from developed countries and the absorption of their advantages for innovation; and second, the development process from small to large, from experimental to full commercialization. Wind power generation is moving towards the goal of high-quality development. Although my country's wind power generation has made great progress, there are still many prominent engineering problems in the development process, mainly manifested in the following aspects: (1) Wind measurement data is relatively lacking and needs to be improved, which will directly affect the power generation efficiency of wind power; (2) The standards for wind power generation need to be improved, and the applicability of related design methods needs to be verified; (3) The foundation of wind turbines is greatly affected by topography, underground structure, groundwater and adverse geological effects.

[0004] During field surveys of wind turbine foundations, some areas contain Carboniferous and Permian limestone. This limestone is relatively pure, with well-developed karst formations, resulting in complex engineering geological conditions and a high risk of geological disasters such as karst ground collapse. Deep karst caves, when dry, often display stalactites, stalagmites, and columns, and their walls are often slanted. Such karst development areas significantly impact the project, affecting its quality, and are a crucial factor to consider during site selection.

[0005] Because the location of the wind turbine foundation is characterized by karst development and a thin overburden layer consisting of a single layer of cohesive soil, karst ground subsidence can easily occur due to factors such as construction work or significant fluctuations in groundwater levels. Therefore, hidden karst is one of the most significant adverse engineering geological problems in the construction of wind turbine foundations. Hidden karst caves have an extremely adverse impact on the safety of wind power projects and require specialized investigation to determine the development of hidden karst caves in the limestone distribution area and to implement engineering treatment.

[0006] Therefore, constructing wind turbine foundations in areas with highly developed karst is a challenging engineering project. The development of karst can cause deformation of the foundations, affecting the quality of the project and potentially leading to karst ground subsidence, foundation collapse, and even turbine toppling. Therefore, geological surveys of areas with highly developed karst are essential before constructing wind turbine foundations. Currently, domestic methods for karst exploration mainly include geophysical exploration, drilling, and borehole photography. Drilling, in particular, utilizes various engineering drilling rigs. During drilling, samples of soil and rock at different depths need to be taken for analysis. However, manually tapping the drill rod to extract these samples is time-consuming and labor-intensive, significantly reducing the efficiency of drilling and sampling. Therefore, there is an urgent need to design a surveying device for wind turbine foundations that can greatly improve drilling and sampling efficiency. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a wind turbine foundation surveying device, which aims to solve the problems mentioned above.

[0008] This invention provides a wind turbine foundation surveying device, including a drilling machine and a drill rod, a multi-link moving mechanism, and an annular frame with an opening. The multi-link moving mechanism is rotatably mounted on the drilling machine, and the annular frame is rotatably mounted on the multi-link moving mechanism. An arc-shaped frame for closing with the opening is rotatably mounted on the annular frame, and a rotating striking mechanism for striking the drill rod is mounted on the arc-shaped frame. An annular gear is rotatably mounted inside the arc-shaped frame, and a notch is provided on one side of the annular gear. The annular gear is connected to a drive motor mounted on the annular frame. The arc-shaped frame is connected to both ends of the annular gear through connecting rods.

[0009] Furthermore, the ring frame includes an upper ring frame and a lower ring frame. The upper ring frame is connected to the lower ring frame through a telescopic tube, which is rotatably located at the end of the multi-link moving mechanism. Ring gears are rotatably located in the upper and lower ring frames respectively. A drive motor is located on the upper ring frame and connected to the ring gear thereon. A first telescopic component is provided on the lower ring frame, and the output end of the first telescopic component is fixedly connected to the upper ring frame. The rotating striking mechanism includes a striking motor, a striking hammer, a ring-shaped component, a transmission gear, and a forward-rotating gear with several teeth. A mounting plate protrudes from the arc-shaped frame. The striking motor is located on one side of the mounting plate. One end of the striking hammer is rotatably mounted between the mounting plates via a first rotating shaft. The ring-shaped component is rotatably mounted on one side of the mounting plate, and the forward-rotating gear is rotatably mounted on the other side of the mounting plate. The ring-shaped component and the forward-rotating gear are connected via a second rotating shaft. The striking motor and the forward-rotating gear are coaxially connected. The ring-shaped component has an annular groove with several teeth on its inner and outer rings. Transmission gears are located at both ends of the first rotating shaft. One transmission gear is located in the annular groove and intermittently meshes with the teeth in the annular groove, while the other transmission gear intermittently meshes with the forward-rotating gear.

[0010] Furthermore, it also includes a transverse striking mechanism, which is mounted on an arc-shaped frame. A drive gear is mounted on the second rotating shaft, and the transverse striking mechanism meshes with the drive gear for transmission. The transverse striking mechanism includes an arc-shaped striking block, a push tube, a push rod, a swing rod, and a driven gear. The arc-shaped striking block is slidably mounted on the arc-shaped frame via the push tube. The push rod is slidably mounted inside the push tube, and a first spring is installed inside the push tube. One end of the first spring is connected to the end of the push rod. One end of the swing rod is hinged to the end of the push rod. The driven gear is rotatably mounted between the mounting plates, and the other end of the swing rod is hinged between the driven gears, so that the driven gear, through rotation, pushes the swing rod to drive the push rod to move linearly, thereby driving the arc-shaped striking block to perform transverse reciprocating motion. The end of the striking hammer is provided with a sleeve and a striking part, and the striking part is mounted inside the sleeve via a second spring.

[0011] Furthermore, it also includes an arc-shaped clamping block, which is slidably mounted on the upper annular frame. The upper annular frame is equipped with a second telescopic component, the output end of which is connected to the arc-shaped clamping block. The lower end of the upper annular frame and the interior of the lower annular frame are provided with annular limiting grooves for limiting the annular gear. The lower end of the upper annular frame and the upper end of the lower annular frame are provided with arc-shaped grooves that communicate with the annular limiting grooves. A connecting rod passes through the arc-shaped grooves and connects to the arc-shaped frame. The first and second telescopic components are electric cylinders or hydraulic cylinders; the connecting rod includes an upper connecting rod and a lower connecting rod. The upper connecting rod is fixedly connected to the upper end face of the arc-shaped frame, and the lower connecting rod is slidably connected to the lower end face of the arc-shaped frame.

[0012] Furthermore, the multi-link moving mechanism includes a primary link and a secondary link. The primary link is rotatably mounted on the drilling rig, and the secondary link is rotatably mounted at both ends of the primary link; the telescopic tube is rotatably mounted at the end of the secondary link.

[0013] Compared with existing technologies, it has the following beneficial effects:

[0014] This invention provides a wind turbine foundation surveying device. A multi-link moving mechanism is rotatably connected to a drilling rig, and an open ring frame is rotatably mounted on the multi-link moving mechanism to allow the ring frame to be fitted onto the drill rod through the opening. Simultaneously, an arc-shaped frame is mounted on the ring frame. Driven by a motor, a notched ring gear on the arc-shaped frame rotates the arc-shaped frame, allowing a rotating striking mechanism on the arc-shaped frame to strike the drill rod and extract samples from inside. Furthermore, a transverse striking mechanism is included to strike the drill rod at different positions along its axial direction, effectively improving the sampling efficiency of soil and rock samples from inside the drill rod and significantly reducing manual labor.

Detailed Implementation

[0032] To better understand the structure, functional features, and advantages of the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

[0033] Example 1:

[0034] like Figures 1 to 15As shown, the present invention provides a wind turbine foundation surveying device, including a drilling machine and a drill rod, and further including a multi-link moving mechanism 1 and an annular frame 2 with an opening. The multi-link moving mechanism 1 is rotatably mounted on the drilling machine, and the annular frame 2 is rotatably mounted on the multi-link moving mechanism 1. An arc-shaped frame 3 for closing with the opening is rotatably mounted on the annular frame 2, and a rotating striking mechanism for striking the drill rod is mounted on the arc-shaped frame 3. An annular gear 4 is rotatably mounted inside the arc-shaped frame 3, and a notch is provided on one side of the annular gear 4. The annular gear 4 is connected to a drive motor 5 mounted on the annular frame 2. The arc-shaped frame 3 is connected to both ends of the annular gear 4 through a connecting rod 6, so that the drive motor 5 can drive the annular gear 4 to rotate the arc-shaped frame 3 between the annular frames 2 to form a circular closed frame structure.

[0035] Preferably, the ring frame 2 includes an upper ring frame 21 and a lower ring frame 22. The upper ring frame 21 is connected to the lower ring frame 22 through a telescopic tube 7, which is rotatably disposed at the end of the multi-link moving mechanism 1. The ring gear 4 is rotatably disposed in the upper ring frame 21 and the lower ring frame 22 respectively. The drive motor 5 is disposed on the upper ring frame 21 and connected to the ring gear 4 thereon. The lower ring frame 22 is provided with a first telescopic component 8, and the output end of the first telescopic component 8 is fixedly connected to the upper ring frame 21. The rotating striking mechanism includes a striking motor 41, a striking hammer 42, an annular component 43, a transmission gear 44, and a forward rotating gear 45 with several teeth. A mounting plate 9 protrudes from the arc-shaped frame 3. The striking motor 41 is located on one side of the mounting plate 9. One end of the striking hammer 42 is rotatably mounted between the mounting plates 9 via a first rotating shaft 46. The annular component 43 is rotatably mounted on one side of the mounting plate 9, and the forward rotating gear 45 is rotatably mounted on the other side of the mounting plate 9. The annular component 43 and the forward rotating gear 45 are connected by a second rotating shaft 47. The striking motor 41 and the forward rotating gear 45 are coaxially connected. The annular component 43 has an annular groove 48, and the inner and outer rings of the annular groove 48 have several teeth. The two ends of the first rotating shaft 46 are provided with transmission gears 44. One transmission gear 44 is located in the annular groove 48 and intermittently meshes with the teeth in the annular groove 48. The other transmission gear 44 intermittently meshes with the forward rotating gear 45. Specifically, the striking motor 41 drives the clockwise rotating gear 45 to rotate clockwise, which in turn drives the ring 43 to rotate clockwise via the second rotating shaft 47. During rotation, the teeth on the ring 43 mesh with one of its transmission gears 44, causing the striking hammer 42 to swing counterclockwise to strike the drill pipe. As the striking motor 41 continues to rotate clockwise, when the striking hammer 42 reaches its lowest point, the teeth on the ring 43 disengage from the transmission gear 44 on one side. At this time, the teeth on the clockwise rotating gear 45 mesh with the transmission gear 44 on the other side, causing the transmission gear 44 to rotate counterclockwise to swing the striking hammer 42 up. When the striking hammer 42 reaches its highest point, the teeth on the clockwise rotating gear 45 disengage from the transmission gear 44, and the transmission gear 44 on one side of the ring 43 meshes with the teeth inside the ring 43, causing the ring 43 to drive the transmission gear 44 to rotate clockwise, causing the striking hammer 42 to swing clockwise to strike the drill pipe. Furthermore, the outer ring of the inner annular groove 48 of the annular component 43 is provided with two sets of teeth facing each other, and the forward rotating gear 45 is provided with one set of teeth. Since the diameter of the forward rotating gear 45 is smaller than the diameter of the outer ring of the annular groove 48, this method can realize the rapid descent of the hammer 42 to strike the drill rod, and the slow rise to prepare for the next strike.The end of the hammer 42 is provided with a sleeve 421 and a striking part 422. The striking part 422 is located inside the sleeve 421 through a second spring 423 to reduce the force transmitted to the striking rod during the striking process, thereby reducing the rebound of the hammer 42. Furthermore, in order to further reduce the rebound of the hammer 42, a hydraulic buffer mechanism can be added to the striking rod to reduce the problem of accelerated wear caused by the impact of the hammer 42 during the striking process, which causes the transmission gear 44 to hit the teeth. This effectively ensures the stable fit between the teeth.

[0036] Preferably, the multi-link moving mechanism 1 includes a primary link 101 and a secondary link 102. The primary link 101 is rotatably mounted on the drilling rig, and the secondary link 102 is rotatably mounted at both ends of the primary link 101. The telescopic tube 7 is rotatably mounted at the end of the secondary link 102. The telescopic tube 7 includes an outer tube and a telescopic rod. The outer tube is rotatably connected to the secondary link 102, the lower annular frame 22 is connected to the outer tube, the telescopic rod is slidably mounted inside the outer tube, and the upper annular frame 21 is fixedly connected to the telescopic rod, so that the first telescopic component 8 can drive the upper annular frame 21 and the lower annular frame 22 to move relative to each other. The rotation of the connection between the primary link 101 and the secondary link 102 can be controlled by a motor; similarly, the rotation of the annular frame 2 can be controlled by a motor at the connection between the secondary link 102 and the telescopic tube 7, by setting an annular gear 4 on the outer tube and setting a motor that is connected to the annular gear 4 at the end of the secondary link 102.

[0037] Example 2:

[0038] like Figure 5 and Figure 14 As shown, in conjunction with the technical solution of Embodiment 1, this embodiment also includes a transverse striking mechanism. The transverse striking mechanism is mounted on the arc-shaped frame 3, and a drive gear 49 is mounted on the second rotating shaft 47. The transverse striking mechanism meshes with the drive gear 49 for transmission. The transverse striking mechanism includes an arc-shaped striking block 51, a push tube 52, a push rod 53, a swing rod 54, and a driven gear 55. The arc-shaped striking block 51 is slidably mounted on the arc-shaped frame 3 via the push tube 52. The push rod 53 is slidably mounted inside the push tube 52. A first spring 56 is mounted inside the push tube 52, and one end of the first spring 56 is connected to the end of the push rod 53. By setting the first spring 56, the reaction force transmitted from the arc-shaped striking block 51 to the push rod 53 is reduced, effectively improving the service life of the transverse striking mechanism. One end of the swing rod 54 is hinged to the end of the push rod 53. The driven gear 55 is rotatably mounted between the mounting plates 9. The other end of the swing rod 54 is hinged to the driven gear 55, so that the driven gear 55 rotates to push the swing rod 54 to drive the push rod 53 to move linearly, thereby pushing the arc-shaped striking block 51 to move laterally and reciprocate, thus vibrating and striking the drill rod. Combined with the action of the striking hammer 42, the drill rod is struck at two places at the same time, which effectively improves the removal of samples such as stones and hard blocks stuck in the drill rod.

[0039] Example 3:

[0040] like Figures 1 to 12 As shown, in conjunction with the technical solution of Embodiment 2, this embodiment further includes an arc-shaped clamping block 11, which is slidably mounted on the upper annular frame 21. The upper annular frame 21 is provided with a second telescopic component 10, the output end of which is connected to the arc-shaped clamping block 11. The second telescopic component 10 drives the arc-shaped clamping block 11 to clamp drill rods of different diameters. The arc-shaped clamping block 11 clamps the drill rods by combining with the arc-shaped frame 3. Further, multiple arc-shaped clamping blocks 11 can be provided and arranged at a certain angle on the upper arc-shaped frame 3 to facilitate simultaneous clamping of drill rods. The lower end of the upper annular frame 21 and the lower annular frame 22 are provided with annular limiting grooves 12 for limiting the annular gear 4. The lower end of the upper annular frame 21 and the upper end of the lower annular frame 22 are provided with arc-shaped grooves 13, which communicate with the annular limiting grooves 12. The connecting rod 6 passes through the arc-shaped grooves 13 and connects to the arc-shaped frame 3. Furthermore, the lower part of the arc-shaped clamping block 11 can be slidably connected to the lower part of the upper annular frame 21 via a limiting rod to limit the arc-shaped clamping block 11. The first telescopic component 8 and the second telescopic component 10 are electric cylinders or hydraulic cylinders; the connecting rod 6 includes an upper connecting rod and a lower connecting rod, the upper connecting rod is fixedly connected to the upper end face of the arc-shaped frame 3, and the lower connecting rod is slidably connected to the lower end face of the arc-shaped frame 3. By setting the first telescopic component 8, the distance between the upper annular frame 21 and the lower annular frame 22 can be adjusted, and the arc-shaped clamping block 11 can be used to lift the drill rod and then make it swing vertically up and down to remove the sample from the drill rod. Furthermore, the lower annular frame 22 is provided with an elastic sleeve to reduce the force transmitted to the annular frame 2 when the hammer 42 strikes. Furthermore, the arc-shaped clamping block 11 can be elastically configured to provide a buffering effect.

[0041] Specifically, such as Figures 10 to 13 It also includes a magnetic lock 14, which is located on the upper end face of the lower annular frame 22 and fixed to the telescopic tube 7. The annular gear 4 located inside the lower annular frame 22 has multiple locking holes 15 along its axial direction. The magnetic lock 14 has a locking rod that passes through a circular hole on the lower annular frame 22 and engages with the locking hole 15 to lock the annular gear 4, thereby locking the rotational freedom of the arc-shaped frame 3. The magnetic lock 14 contains an iron rod wound with a wire. When the wire is energized, the iron rod becomes magnetic, attracting a permanent magnet. This causes the locking rod connected to the permanent magnet to retract and disengage from the locking hole 15, unlocking the rotational freedom of the annular gear 4. When the wire is de-energized, the insert rod sleeved on the spring returns to its original position under the spring force and engages with the locking hole 15.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.
