Description

Technical Field

[0001] This invention belongs to the field of wind power construction technology, and in particular relates to a precise positioning and closing device for the mid-section closing joint of a wind turbine jacket. Background Technology

[0002] When constructing an offshore wind power station, a fixed offshore platform must first be erected, and then the wind power generation equipment is installed on the platform. To ensure the stability of the offshore platform, a jacket structure is required. During the construction of the jacket structure, two ducts need to be welded together at their ends.

[0003] In existing technology, when performing conduit butt welding, one conduit is first fixed with a clamp, then the other conduit is manually moved to the corresponding position to align the ends of the two conduits. Next, the other conduit is fixed with another clamp, and finally, the ends of the two conduits are welded together using an electric welding machine. The clamp includes a first clasping block and a second clasping block, which are threaded together by a threaded post. The first clasping block is positioned either closer to or away from the second clasping block along the axial direction of the threaded post. When using this clamp to fix the conduit, the conduit is first placed on the second clasping block, and then the threaded post is rotated to bring the first clasping block closer to the second clasping block, thereby clamping and fixing the conduit. Because the conduit is relatively heavy, two threaded posts are provided to clamp it more tightly.

[0004] This means that when clamping the catheter, it is necessary to rotate the two threaded pins separately to fix the catheter, which makes the process of fixing the catheter more complicated and time-consuming, thus reducing the work efficiency of the staff. Summary of the Invention

[0005] The purpose of this invention is to provide a precise positioning and closing device for the mid-section closing joint of a wind turbine jacket. When clamping the jacket, this device rotates one threaded post, which in turn rotates another threaded post, causing the first and second closing blocks to close and clamp the jacket. This simplifies the process of fixing the jacket while ensuring it is securely fixed, reduces the time required, and thus improves the efficiency of jacket fixing.

[0006] To achieve the above objectives, the present invention is implemented as follows:

[0007] This invention provides a precise positioning and closing device for the mid-section closing joint of a wind turbine jacket. The closing device includes: a first closing block, a second closing block, a first threaded post, a second threaded post, a first transmission wheel, a second transmission wheel, a transmission belt, a fixing plate, and a side extension plate.

[0008] The first closing block is provided with a through first threaded hole and a through second threaded hole; the second closing block is provided with a third threaded hole and a fourth threaded hole, the axis of the second threaded hole, the axis of the third threaded hole and the axis of the fourth threaded hole are all parallel to the axis of the first threaded hole, the axis of the first threaded hole and the third threaded hole coincide and have the same diameter, and the axis of the second threaded hole and the fourth threaded hole coincide and have the same diameter.

[0009] The first closing block moves away from or closer to the second closing block along the axial direction of the first threaded hole. When the first closing block is close to the second closing block, it forms a first clamping channel, which is used to clamp the conduit. The first threaded post passes through the first threaded hole and is threadedly connected to the third threaded hole. The second threaded post passes through the second threaded hole and is threadedly connected to the fourth threaded hole.

[0010] The first drive wheel is fixedly connected to the end of the first threaded post opposite to the second closing block; the second drive wheel is fixedly connected to the end of the second threaded post opposite to the second closing block; the drive belt is sleeved on the first drive wheel and the second drive wheel, and when one of the first drive wheel and the second drive wheel rotates, it drives the other to rotate through the drive belt.

[0011] A groove is provided on the surface of the fixing plate near the first closing block, and the groove extends parallel to the axis of the first threaded hole. A slider is provided on the surface of the first closing block near the fixing plate, and the slider is slidably connected to the groove. The side extension plate is spliced ​​and connected to the fixing plate.

[0012] Optionally, the slider is detachably connected to the groove, and the plane where the side extension plate is located is parallel to the plane where the fixed plate is located.

[0013] Optionally, the precise positioning and closing device for the mid-section closing joint of the wind turbine jacket further includes a first clamp, a second clamp, and a transmission assembly, wherein the transmission assembly drives the first clamp to the first closing block.

[0014] When the first closing block moves away from or nears the second closing block along the axial direction of the first threaded hole, the transmission assembly drives the first clamp to move away from or near the second clamp along the axial direction of the first threaded hole.

[0015] When the first clamp approaches the second clamp, it forms a second clamping channel, which is used to clamp the catheter.

[0016] Optionally, the transmission assembly includes: a power rod, a first gear, a first bevel gear, a threaded rod, a second bevel gear, and a rack, wherein the rack is fixedly connected to the first closing block; the first gear is sleeved and fixedly mounted on the power rod, and the first gear meshes with the rack; the end of the power rod is fixedly connected to the first bevel gear, and the second bevel gear meshes with the first bevel gear;

[0017] The first end of the threaded rod is inserted into the second bevel gear, and the inner ring surface of the second bevel gear is threadedly connected to the threaded rod. The second end of the threaded rod is fitted with a rotating ring, which is rotatably connected to the threaded rod. A connecting rod is fixedly provided on the outer wall of the rotating ring, and the connecting rod is fixedly connected to the first clamp.

[0018] Optionally, the first clamp slidably abuts against the side extension plate.

[0019] Optionally, the side extension plate is provided with a travel limiting hole, the travel limiting hole is strip-shaped, and the extension direction of the travel limiting hole is parallel to the axis of the first threaded hole;

[0020] The connecting rod passes through the travel limiting hole, and the connecting rod is slidably connected to the travel limiting hole.

[0021] Optionally, the precise positioning and closing device for the mid-section closing opening of the wind turbine jacket further includes a snap-fit ​​assembly. One of the first closing block and the second closing block is fixedly connected to the snap-fit ​​assembly, and the other is provided with a mounting hole. When the first closing block and the second closing block are closed, the snap-fit ​​assembly is inserted into the mounting hole and abuts against the inner wall of the mounting hole.

[0022] The snap-fit ​​assembly includes a conical block and a hollow cylinder. The conical block is inserted into the hollow cylinder and slidably connected to the inner wall of the hollow cylinder. The inner diameter of the hollow cylinder is the same as the outer diameter of the conical block, and the tip of the conical block is located on the outer side of the hollow cylinder.

[0023] The conical block is inserted into the hollow cylinder at one end and is provided with a first telescopic rod, a first spring, an elastic element, and a limiting pin. The axis of the first telescopic rod is perpendicular to the axis of the first threaded hole. Both ends of the first telescopic rod are provided with elastic elements. The limiting pin is provided on the outside of the elastic element along the axis of the first telescopic rod. The first spring is sleeved on the first telescopic rod and both ends of the first spring are fixedly connected to the elastic element. The elastic element extends and retracts along the axis of the first telescopic rod.

[0024] The hollow cylinder has a through hole on its side wall, and the limiting pin passes through the through hole;

[0025] The inner wall of the mounting hole is provided with a limiting hole. When the buckle assembly is inserted into the mounting hole, the elastic element is squeezed and elongated so that the limiting pin is inserted into the limiting hole.

[0026] Optionally, the end of the conical block inserted into the hollow cylinder is further provided with a second telescopic rod, a second spring, and a pressing block; the second spring is sleeved on the second telescopic rod, the axis of the second telescopic rod is parallel to the axis of the first threaded hole, the first end of the second spring is fixedly connected to the conical block, and the second end of the second spring is fixedly connected to the insertion end of the second telescopic rod;

[0027] The compression block abuts against or separates from the elastic element. When the compression block abuts against the elastic element, the elastic element is compressed and elongated.

[0028] Optionally, positioning protrusions are fixedly installed on the inner walls of both the first and second merging blocks.

[0029] Optionally, an annular limiting groove is provided on the outer ring surface of both the first transmission wheel and the second transmission wheel, and the width of the annular limiting groove is the same as the width of the transmission belt.

[0030] Optionally, both the first and second drive wheels are pulleys, and the drive belt is a belt.

[0031] In this embodiment, the first closing block has a through first threaded hole and a through second threaded hole; the second closing block has a third threaded hole and a fourth threaded hole. The axes of the second, third, and fourth threaded holes are all parallel to the axis of the first threaded hole. The axes of the first and third threaded holes coincide and have the same diameter, as do the axes of the second and fourth threaded holes. A first threaded post passes through the first threaded hole and is threadedly connected to the third threaded hole; a second threaded post passes through the second threaded hole and is threadedly connected to the fourth threaded hole. Thus, by rotating the first and second threaded posts, the first closing block can move away from or closer to the second closing block along the axis of the first threaded hole, thereby achieving the closing or separation of the first and second closing blocks.

[0032] Next, as the first closing block approaches the second closing block, it forms a first clamping channel, which is used to clamp the conduit. When the conduit is clamped in the first clamping channel, it can be fixed, thus the closing device achieves the purpose of fixing the conduit. Furthermore, because the closing device has two threaded posts, it allows the conduit to be clamped more securely compared to a solution with only one threaded post.

[0033] Next, since the first drive wheel is fixedly connected to the end of the first threaded post opposite to the second closing block; and the second drive wheel is fixedly connected to the end of the second threaded post opposite to the second closing block; and a drive belt is sleeved on the first and second drive wheels, when one of the first and second drive wheels rotates, it drives the other to rotate via the drive belt. Thus, when either the first or second drive wheel rotates, the other can also rotate via the drive belt, thereby achieving the simultaneous rotation of both threaded posts. Compared to related technologies where two threaded posts need to be rotated separately to fix the conduit, this method simplifies the process of fixing the conduit while ensuring its secure fixation, reduces the time required, and improves the efficiency of fixing the conduit.

[0034] The above description is merely an overview of the technical solution of the present invention.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0047] The precise positioning and closing device 100 for the mid-section closing joint of the wind power jacket provided in this invention will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0048] Figure 1 This is a schematic diagram of the structure of a precise positioning and closing device 100 for the mid-section closing opening of a wind turbine jacket provided in an embodiment of the present invention.

[0049] See Figure 1 The closing device 100 includes: a first closing block 1, a second closing block 2, a first threaded post 3, a second threaded post 4, a first transmission wheel 5, a second transmission wheel 6, a transmission belt 7, a fixing plate 11, and a side extension plate 15.

[0050] The first closing block 1 is provided with a through first threaded hole 101 and a through second threaded hole 102; the second closing block 2 is provided with a third threaded hole 201 and a fourth threaded hole. The axis of the second threaded hole 102, the axis of the third threaded hole 201 and the axis of the fourth threaded hole are all parallel to the axis of the first threaded hole 101. The axes of the first threaded hole 101 and the third threaded hole 201 coincide and have the same diameter. The axes of the second threaded hole 102 and the fourth threaded hole coincide and have the same diameter.

[0051] The first closing block 1 moves away from or closer to the second closing block 2 along the axial direction of the first threaded hole 101. When the first closing block 1 is close to the second closing block 2, it forms a first clamping channel 8, which is used to clamp the guide tube. The first threaded post 3 passes through the first threaded hole 101 and is threadedly connected to the third threaded hole 201. The second threaded post 4 passes through the second threaded hole 102 and is threadedly connected to the fourth threaded hole.

[0052] The first drive wheel 5 is fixedly connected to the end of the first threaded post 3 that is away from the second closing block 2; the second drive wheel 6 is fixedly connected to the end of the second threaded post 4 that is away from the second closing block 2; the drive belt 7 is sleeved on the first drive wheel 5 and the second drive wheel 6, and when one of the first drive wheel 5 and the second drive wheel 6 rotates, it drives the other to rotate through the drive belt 7.

[0053] A groove 111 is provided on the surface of the fixing plate 11 near the first closing block 1. The extension direction of the groove 111 is parallel to the axis of the first threaded hole 101. A slider 103 is provided on the surface of the first closing block 1 near the fixing plate 11. The slider 103 is slidably connected to the groove 111. The side extension plate 15 is spliced ​​and connected to the fixing plate 11.

[0054] In this embodiment, the first closing block 1 is provided with a through first threaded hole 101 and a through second threaded hole 102; the second closing block 2 is provided with a third threaded hole 201 and a fourth threaded hole. The axes of the second threaded hole 102, the third threaded hole 201, and the fourth threaded hole are all parallel to the axis of the first threaded hole 101. The axes of the first threaded hole 101 and the third threaded hole 201 coincide and have the same diameter, and the axes of the second threaded hole 102 and the fourth threaded hole coincide and have the same diameter. The first threaded post 3 passes through the first threaded hole 101 and is threadedly connected to the third threaded hole 201; the second threaded post 4 passes through the second threaded hole 102 and is threadedly connected to the fourth threaded hole. Thus, by rotating the first threaded post 3 and the second threaded post 4, the first closing block 1 can move away from or closer to the second closing block 2 along the axis of the first threaded hole 101, thereby realizing the closing or separation of the first closing block 1 and the second closing block 2.

[0055] Next, when the first closing block 1 approaches the second closing block 2, it forms a first clamping channel 8, which is used to clamp the conduit. When the conduit is clamped in the first clamping channel 8, it can be fixed, thus the closing device 100 achieves the purpose of fixing the conduit. Furthermore, since the closing device 100 is provided with two threaded posts, compared to a solution with only one threaded post, the conduit can be clamped more securely.

[0056] Next, since the first drive wheel 5 is fixedly connected to the end of the first threaded post 3 opposite to the second closing block 2; and the second drive wheel 6 is fixedly connected to the end of the second threaded post 4 opposite to the second closing block 2; and the drive belt 7 is sleeved on the first drive wheel 5 and the second drive wheel 6, when one of the first drive wheel 5 and the second drive wheel 6 rotates, it drives the other to rotate via the drive belt 7. Thus, when either the first drive wheel 5 or the second drive wheel 6 is rotated, the other can also be driven to rotate via the drive belt 7, thereby achieving the purpose of simultaneously rotating both threaded posts. Compared to related technologies where two threaded posts need to be rotated separately to fix the conduit when clamping it, this method simplifies the process of fixing the conduit, reduces the time required for fixing the conduit, and thus improves the efficiency of fixing the conduit, while ensuring that the conduit is firmly fixed.

[0057] Next, a groove 111 is provided on the surface of the fixing plate 11 near the first closing block 1, and a slider 103 is provided on the surface of the first closing block 1 near the fixing plate 11. The slider 103 is slidably connected to the groove 111. Thus, when the slider 103 slides relative to the groove 111, it can drive the first closing block 1 to slide relative to the fixing plate 11. Furthermore, since the extension direction of the groove 111 is parallel to the axis of the first threaded hole 101, the sliding direction of the slider 103 is the same as the closing or separating direction of the first closing block 1 and the second closing block 2, thereby guiding the closing or separating process and making the closing or separating process smoother.

[0058] Next, the side extension plate 15 is spliced ​​and connected to the fixing plate 11. This effectively increases the area of ​​the fixing plate 11, thereby providing ample space for installing other components.

[0059] It should be noted that the first transmission wheel 5 and the second transmission wheel 6 mentioned above can be pulleys, in which case the transmission belt 7 is a belt. Alternatively, the first transmission wheel 5 and the second transmission wheel 6 mentioned above can be gears, in which case the transmission belt 7 is a chain. This application does not limit the specific type of transmission wheel 7.

[0060] It should also be noted that the number of threaded holes provided in the first closing block 1 and the second closing block 2 can be increased, such as three, four or more, and the number of corresponding threaded posts can also be increased accordingly. The specific number is not limited in this embodiment. Adjacent threaded posts are connected by a transmission wheel and a transmission belt 7.

[0061] Alternatively, in some embodiments, see Figure 1 and Figure 2 The slider 103 and the slide groove 111 are detachably connected, and the plane where the side extension plate 15 is located is parallel to the plane where the fixed plate 11 is located.

[0062] In this embodiment, since the slider 103 and the slide groove 111 are detachably connected, when the closing device 100 is needed, the slider 103 and the slide groove 111 are connected. When it is not needed, the slider 103 and the slide groove 111 can be separated, thereby enabling the fixing plate 11 to be separated from the first closing block 1, thus facilitating the storage of the closing device 100.

[0063] Next, since the plane where the side extension plate 15 is located is parallel to the plane where the fixed plate 11 is located, the side extension plate 15 and the fixed plate 11 can form a larger plane after being spliced ​​together, thus providing ample space for installing other components.

[0064] Alternatively, in some embodiments, see Figure 1 and Figure 2The wind turbine jacket mid-section closing joint precision positioning and closing device 100 also includes a first clamp 12, a second clamp 13 and a transmission component 14, the transmission component 14 drivingly connecting the first clamp 12 and the first closing block 1.

[0065] When the first closing block 1 moves away from or nears the second closing block 2 along the axial direction of the first threaded hole 101, the transmission assembly 14 drives the first clamp 12 to move away from or near the second clamp 13 along the axial direction of the first threaded hole 101.

[0066] When the first clamp 12 approaches the second clamp 13, it forms a second clamping channel 9, which is used to clamp the catheter.

[0067] In this embodiment, the first clamp 12 can move away from or near the second clamp 13 along the axial direction of the first threaded hole 101, and when the first clamp 12 is near the second clamp 13, it forms a second clamping channel 9, which is used to clamp the conduit. The conduit clamped by the second clamping channel 9 and the conduit clamped by the first clamping channel 8 are two different conduits. When the two conduits are clamped and fixed by the first clamping channel 8 and the second clamping channel 9 respectively, they can be connected together, thus enabling the closing device 100 to perform the function of connecting conduits.

[0068] Next, since the transmission assembly 14 connects the first clamp 12 to the first closing block 1, when the first closing block 1 moves away from or closer to the second closing block 2 along the axial direction of the first threaded hole 101, the transmission assembly 14 drives the first clamp 12 to move away from or closer to the second clamp 13 along the axial direction of the first threaded hole 101. This achieves the transmission between the first closing block 1 and the first clamp 12. When using this closing device 100, the technician only needs to rotate one threaded post to simultaneously achieve the desired result.

[0069] The first closing block 1 approaches the second closing block 2 along the axial direction of the first threaded hole 101, and the first clamp 12 approaches the second clamp 13 along the axial direction of the first threaded hole 101, thus simultaneously forming the first clamping channel 8 and the second clamping channel 9. This improves the efficiency of fixing and connecting the two conduits.

[0070] It should be noted that the first clamping channel 8 and the second clamping channel 9 mentioned above can be cylindrical channels, in which case the clamped conduit is a cylindrical tube. Alternatively, the first clamping channel 8 and the second clamping channel 9 can be prismatic channels, in which case the clamped conduit is a prismatic tube. This application embodiment does not limit this.

[0071] Alternatively, in some embodiments, see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The transmission assembly 14 includes: a power rod 141, a first gear 142, a first bevel gear 143, a threaded rod 144, a second bevel gear 145, and a rack 146. The rack 146 is fixedly connected to the first closing block 1. The first gear 142 is sleeved and fixed on the power rod 141, and the first gear 142 meshes with the rack 146. The end of the power rod 141 is fixedly connected to the first bevel gear 143, and the second bevel gear 145 meshes with the first bevel gear 143.

[0072] The first end of the threaded rod 144 is inserted into the second bevel gear 145. The inner ring surface of the second bevel gear 145 is threadedly connected to the threaded rod 144. The second end of the threaded rod 144 is fitted with a rotating ring 147. The rotating ring 147 is rotatably connected to the threaded rod 144. A connecting rod 148 is fixedly installed on the outer wall of the rotating ring 147. The connecting rod 148 is fixedly connected to the first clamp 12.

[0073] In this embodiment, the rack 146 is fixedly connected to the first engaging block 1, and the first gear 142 is meshed with the rack 146. Thus, when the first engaging block 1 moves closer to the second engaging block 2, it can drive the rack 146 to move towards the second engaging block 2, thereby driving the first gear 142 to rotate. Then, since the first gear 142 is sleeved and fixed on the power rod 141, the rotation of the first gear 142 can drive the power rod 141 to rotate in the same direction.

[0074] Next, since the end of the power rod 141 is fixedly connected to the first bevel gear 143, and the second bevel gear 145 is meshed with the first bevel gear 143, the rotation of the power rod 141 can drive the first bevel gear 143 to rotate in the same direction, which in turn drives the second bevel gear 145 to rotate. The rotation directions of the second bevel gear 145 and the first bevel gear 143 are different, that is, the rotation axes around which the second bevel gear 145 and the first bevel gear 143 rotate are in different directions. Specifically, the rotation axes around which they rotate are perpendicular.

[0075] Next, since the first end of the threaded rod 144 is inserted into the second bevel gear 145, the inner ring surface of the second bevel gear 145 is threadedly connected to the threaded rod 144. Thus, when the second bevel gear 145 rotates, it can drive the threaded rod 144 to rotate, and the threaded rod 144 can move along its own axis. The axis of the threaded rod 144 is parallel to the axis of the first threaded hole 101, so the threaded rod 144 moves in the same direction as the first closing block 1.

[0076] Next, a rotating ring 147 is fitted onto the second end of the threaded rod 144, and the rotating ring 147 is rotatably connected to the threaded rod 144. The rotating ring 147 cannot move relative to the threaded rod 144 along its axial direction. Thus, when the threaded rod 144 moves along its own axial direction, it can drive the rotating ring 147 to move in the same direction. Furthermore, when the threaded rod 144 moves in the same direction as the first closing block 1, the rotating ring 147 also moves in the same direction as the first closing block 1.

[0077] Next, a connecting rod 148 is fixedly installed on the outer wall of the rotating ring 147, and the connecting rod 148 is fixedly connected to the first clamp 12. Thus, when the rotating ring 147 moves in the same direction as the first closing block 1, the first clamp 12 also moves in the same direction as the first closing block 1.

[0078] Through the aforementioned series of transmission processes, the transmission component 14 enables the first clamp 12 to move in the same direction via the movement of the first closing fastener. Thus, when using the closing device 100, a technician only needs to rotate a threaded post to simultaneously form the first clamping channel 8 and the second clamping channel 9. This improves the efficiency of fixing and connecting two conduits.

[0079] Alternatively, in some embodiments, see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The first clamp 12 slides against the side extension plate 15.

[0080] Thus, when the first clamp 12 approaches or moves away from the second clamp 13, the side extension plate 15 can guide the closing or separating process of the first clamp 12 and the second clamp 13, making the closing or separating process of the first clamp 12 and the second clamp 13 smoother.

[0081] It should be noted that the side extension plate 15 is spliced ​​with the fixing plate 11 along the direction perpendicular to the first threaded hole 101, and after splicing, the fixing plate 11 and the side extension plate 15 form a flat plate.

[0082] Alternatively, in some embodiments, see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The side extension plate 15 is provided with a travel limit hole 151. The travel limit hole 151 is strip-shaped and its extension direction is parallel to the axis of the first threaded hole 101. The connecting rod 148 passes through the travel limit hole 151 and is slidably connected to the travel limit hole 151.

[0083] In this embodiment, the side extension plate 15 is provided with a travel limiting hole 151, and the connecting rod 148 passes through the travel limiting hole 151, with the connecting rod 148 slidably connected to the travel limiting hole 151. Thus, when the connecting rod 148 slides relative to the side extension plate 15 along the travel limiting hole 151, it can also drive the first clamp 12 to slide along the travel limiting hole 151. Furthermore, since the travel limiting hole 151 is strip-shaped, its extension direction is parallel to the axis of the first threaded hole 101. This guides the closing and separating of the first clamp 12 and the second clamp 13, making the closing or separating process of the first clamp 12 and the second clamp 13 smoother.

[0084] Alternatively, in some embodiments, see Figure 2 , Figure 6 and Figure 7 The wind turbine duct frame mid-section closing joint precision positioning and closing device 100 also includes a snap-fit ​​assembly 16. One of the first closing block 1 and the second closing block 2 is fixedly connected to the snap-fit ​​assembly 16, and the other is provided with a mounting hole 17. When the first closing block 1 and the second closing block 2 are closed, the snap-fit ​​assembly 16 is inserted into the mounting hole 17 and abuts against the inner wall of the mounting hole 17. The snap-fit ​​assembly 16 includes a conical block 161 and a hollow cylinder 162. The conical block 161 is inserted into the hollow cylinder 162 and is slidably connected to the inner wall of the hollow cylinder 162. The inner diameter of the hollow cylinder 162 is the same as the outer diameter of the conical block 161, and the tip of the conical block 161 is located on the outer side of the hollow cylinder 162.

[0085] A first telescopic rod 163, a first spring 164, an elastic element 165, and a limiting pin 166 are provided at one end of the conical block 161 inserted into the hollow cylinder 162. The axis of the first telescopic rod 163 is perpendicular to the axis of the first threaded hole 101. Both ends of the first telescopic rod 163 are provided with elastic elements 165. The limiting pin 166 is provided on the outside of the elastic element 165 along the axial direction of the first telescopic rod 163. The first spring 164 is sleeved on the first telescopic rod 163. Both ends of the first spring 164 are fixedly connected to the elastic element 165. The elastic element 165 extends and retracts along the axial direction of the first telescopic rod 163. A through hole 1621 is provided on the side wall of the hollow cylinder 162, and the limiting pin 166 passes through the through hole 1621.

[0086] The inner wall of the mounting hole 17 is provided with a limiting hole 171. When the buckle assembly 16 is inserted into the mounting hole 17, the elastic element 165 is squeezed and elongated so that the limiting pin 166 is inserted into the limiting hole 171.

[0087] In this embodiment, since one of the first closing block 1 and the second closing block 2 is fixedly connected to the latching assembly 16, and the other is provided with a mounting hole 17, when the first closing block 1 and the second closing block 2 are closed, the latching assembly 16 is inserted into the mounting hole 17 and abuts against the inner wall of the mounting hole 17. Thus, the latching assembly 16 can connect the first closing block 1 and the second closing block 2, making the first clamping channel 8 formed when the first closing block 1 and the second closing block 2 are closed more stable. Next, since the latching assembly 16 includes a conical block 161 and a hollow cylinder 162, the conical block 161 is inserted into the hollow cylinder 162, the inner diameter of the hollow cylinder 162 is the same as the outer diameter of the conical block 161, and the tip of the conical block 161 is located on the outer side of the hollow cylinder 162. Thus, the conical block can move relative to the hollow cylinder 162 along the axial direction of the hollow cylinder 162, thereby allowing the length of the latching assembly to change. Furthermore, the tip of the conical block 161 is located on the outside of the hollow cylinder 162, that is, the tip points towards the mounting hole 17, which makes it easier for the fastening assembly to be inserted into the mounting hole 17.

[0088] Next, since the conical block 161 is inserted into the hollow cylinder 162, one end is provided with a first telescopic rod 163, a first spring 164, an elastic element 165, and a limiting pin 166. The axis of the first telescopic rod 163 is perpendicular to the axis of the first threaded hole 101. Both ends of the first telescopic rod 163 are provided with elastic elements 165. The limiting pin 166 is provided on the outside of the elastic element 165 along the axial direction of the first telescopic rod 163. The first spring 164 is sleeved on the first telescopic rod 163. The two ends of the first spring 164 are respectively fixedly connected to the elastic element 165. The elastic element 165 extends and retracts along the axial direction of the first telescopic rod 163. The side wall of the hollow cylinder 162 is provided with a through hole 1621, and the limiting pin 166 passes through the through hole 1621. The inner wall of the mounting hole 17 is provided with a limiting hole 171. When the snap-fit ​​assembly 16 is inserted into the mounting hole 17, the elastic element 165 is compressed and elongated so that the limiting pin 166 is inserted into the limiting hole 171. Thus, when the first closing block 1 and the second closing block 2 close together, the snap-fit ​​assembly 16 is inserted into the mounting hole 17. At this time, the elastic elements 165 at both ends of the first telescopic rod 163 are compressed and elongate outward along the axial direction of the first telescopic rod 163. Then, since the limiting pin 166 is located on the outside of the elastic element 165 along the axial direction of the first telescopic rod 163, when the elastic elements 165 at both ends of the first telescopic rod 163 elongate outward, they will push the limiting pin 166 to move outward, thereby causing the limiting pin 166 to insert into the limiting hole 171. At this time, the limiting pin 166 can restrict the movement of the first closing block 1 away from the second closing block 2, thereby making the formed first clamping channel 8 more stable.

[0089] When the first threaded post 3 or the second threaded post 4 is rotated to separate the first closing block 1 from the second closing block 2, the squeezing force on the elastic elements 165 at both ends of the first telescopic rod 163 disappears. The elastic elements 165 will contract inward along the axial direction of the first telescopic rod 163. At the same time, since the two ends of the first spring 164 are respectively fixedly connected to the elastic elements 165, the elastic elements 165 extend and retract along the axial direction of the first telescopic rod 163. Thus, the first spring 164 can also provide an inward pulling force to the elastic elements 165, causing the elastic elements 165 to move inward. This will in turn cause the limiting pin 166 to move inward, causing the limiting pin 166 to disengage from the limiting hole 171. At this time, the limiting pin 166 can no longer restrict the movement of the first closing block 1 away from the second closing block 2, causing the buckle assembly 16 to disengage from the mounting hole 17, thereby allowing the first closing block 1 and the second closing block 2 to separate smoothly.

[0090] It should be noted that the aforementioned elastic element 165 can be a rubber block or an elastic plastic block, or other elastic elements 165 with the same function. This application embodiment does not limit this.

[0091] Alternatively, in some embodiments, see [reference needed]. Figure 2 , Figure 6 and Figure 7 The conical block 161 is inserted into the hollow cylinder 162 at one end and is also provided with a second telescopic rod 167, a second spring 168 and a pressing block 169. The second spring 168 is sleeved on the second telescopic rod 167. The axis of the second telescopic rod 167 is parallel to the axis of the first threaded hole 101. The first end of the second spring 168 is fixedly connected to the conical block 161 and the second end of the second spring 168 is fixedly connected to the insertion end of the second telescopic rod 167. The pressing block 169 abuts against or separates from the elastic member 165. When the pressing block 169 abuts against the elastic member 165, the elastic member 165 is compressed and elongated.

[0092] In this embodiment, since the second spring 168 is sleeved on the second telescopic rod 167, the axis of the second telescopic rod 167 is parallel to the axis of the first threaded hole 101, the first end of the second spring 168 is fixedly connected to the conical block 161, and the second end of the second spring 168 is fixedly connected to the insertion end of the second telescopic rod 167, when the buckle assembly 16 is inserted into the mounting hole 17 and abuts against the inner wall of the mounting hole 17, the second spring 168 is compressed, causing the second telescopic rod 167 to shorten, thereby allowing the pressing block 169 to move toward the elastic member 165 and press the elastic member 165, enabling the limiting pin 166 to be inserted into the limiting hole 171.

[0093] When the first closing block 1 is about to separate from the second closing block 2, the second spring 168 returns to its original deformation and extends, pushing the conical block 161 away from the elastic member 165, thereby causing the pressing block 169 to move away from the elastic member 165. At this time, the pressing force on the elastic member 165 disappears. The elastic member 165 will contract inward along the axial direction of the first telescopic rod 163. At the same time, since the two ends of the first spring 164 are fixedly connected to the elastic member 165, the elastic member 165 extends and contracts along the axial direction of the first telescopic rod 163. Thus, the first spring 164 can also provide an inward pulling force to the elastic member 165, causing the elastic member 165 to move inward. This will in turn cause the limiting pin 166 to move inward, causing the limiting pin 166 to disengage from the limiting hole 171.

[0094] Alternatively, in some embodiments, see Figure 1 Positioning protrusions 18 are fixedly installed on the inner walls of both the first closing block 1 and the second closing block 2.

[0095] Because a pair of positioning holes are provided on the outer surface of some of the conduits, positioning protrusions 18 are fixedly installed on the inner walls of both the first closing block 1 and the second closing block 2, and the positions of the positioning protrusions 18 correspond to the positions of a pair of positioning holes when the conduit is clamped in the first clamping channel 8. In this way, the positioning protrusions 18 can restrict the movement of the conduit relative to the first clamping channel 8, thereby making the conduit clamped more stably.

[0096] It should be noted that the number of the positioning protrusions 18 can be one, three or more, and this application embodiment does not limit this.

[0097] Alternatively, in some embodiments, see Figure 1 and Figure 2 Both the first transmission wheel 5 and the second transmission wheel 6 have annular limiting grooves 19 on their outer ring surfaces. The width of the annular limiting grooves 19 is the same as the width of the transmission belt 7.

[0098] In this way, when the first drive wheel 5 and the second drive wheel 6 rotate, the annular limiting groove 19 can limit the transmission belt 7, preventing the transmission belt 7 from detaching from the first drive wheel 5 or the second drive wheel 6. In addition, making the width of the annular limiting groove 19 the same as the width of the transmission belt 7 can prevent the transmission belt 7 from moving in a direction perpendicular to the rotation axis, thereby making the performance of the closing device 100 more stable.

[0099] Alternatively, in some embodiments, see Figure 1 and Figure 2 Both the first drive wheel 5 and the second drive wheel 6 are pulleys, and the drive belt 7 is a belt.

[0100] Because the maximum static friction force at the contact surface between the pulley and the belt is relatively large after the pulley comes into contact with the belt, the belt will not slip relative to the pulley, thus making the performance of the closing device 100 more stable.

[0101] Furthermore, belt drives can effectively mitigate load impacts and reduce the impact on the system caused by sudden load changes, thereby protecting transmission components from damage. Moreover, belt drives offer smoother operation, lower noise and vibration, simpler structure, and are easier to install and maintain; their adjustment process is also more convenient.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
