[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0030] Example 1

[0031] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , a tower connection structure that is easy to install, which includes a No. 1 tower 1, a No. 2 tower 2 is provided above the No. 1 tower 1, a connecting component 3 is provided at the top of the No. 1 tower 1, and a plug-in component 4 is provided at the bottom of the No. 2 tower 2. A sliding component 5 is provided inside the connecting component 3, and the No. 1 connecting hole 61 and the No. 2 connecting hole 62 for fixing on the connecting component 3 and the sliding component 5 are automatically aligned and connected through the sliding component 5, so as to facilitate the passing and fixing of the bolts. A friction coating is provided on the outside of the connecting component 3, the plug-in component 4 and the sliding component 5, which reduces the friction during connection, improves the corrosion resistance of the connecting component 3, the plug-in component 4 and the sliding component 5, and makes the connection tighter;

[0032] The connecting component 3 includes a connecting tube 31 fixed to the top of the No. 1 tower 1, and a connecting groove 32 is opened at the top of the connecting tube 31. A mounting ring 33 is fixed inside the connecting groove 32. The plug-in component 4 includes a fixing ring 41 fixed to the bottom end of the No. 2 tower 2, and a plug-in ring 42 is fixed at the bottom end of the fixing ring 41. The plug-in ring 42 is located inside the connecting groove 32. The connection between the connecting component 3 and the plug-in component 4 is further reinforced by the sliding component 5. The connection between the connecting component 3 and the plug-in component 4 and the splicing of the sliding component 5 make the installation more convenient and the firmness after the connection is increased. The friction coating can make the connecting component 3 and the plug-in component 4 fit tightly.

[0033] Further, such as Figure 2 、 Figure 3 and Figure 4 As shown, the sliding assembly 5 includes a plurality of connecting blocks 51, which are fixed at equal distances on the top of the mounting ring 33. A fixing block 52 is provided between the connecting blocks 51. The connecting blocks 51 are in contact with adjacent fixing blocks 52, and the fixing blocks 52 are fixedly connected to the plug-in ring 42. The engagement and splicing between the connecting blocks 51 and the fixing blocks 52 further increase the contact area, thereby increasing the stability and firmness after installation and connection.

[0034] Further, such as Figure 2 、 Figure 3 、 Figure 4 and Figure 7 As shown, chamfers are provided at the two edges at the top of the connecting groove 32, and the chamfers make the upper entrance of the connecting groove 32 larger. During installation, the bottom end of the plug-in ring 42 will contact the chamfers at the edge of the connecting groove 32 and slide into the interior of the connecting groove 32 through the chamfers, which can assist in calibrating the position during installation, thereby automatically splicing. A No. 2 guide ring 44 is fixedly provided on the upper part of the interior of the plug-in ring 42, and the No. 2 guide ring 44 is fixedly connected to the bottom end of the No. 2 tower 2. A No. 1 guide ring 43 is fixedly provided on the upper part of the outside of the plug-in ring 42, and the No. 1 guide ring 43 is fixedly connected to the bottom end of the No. 2 tower 2. The No. 1 guide ring 43 and the No. 2 guide ring 44 are respectively in contact with the chamfers at the edge of the connecting groove 32, and the shapes of the No. 1 guide ring 43 and the No. 2 guide ring 44 match the chamfers at the edge of the connecting groove 32, so that they can fit and splice normally.

[0035] Further, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, inclined surfaces are provided on both sides of the top of the connecting block 51. The inclined surfaces increase the space for the fixing block 52 to enter, thereby increasing the fault tolerance of the fixing block 52. When the fixing block 52 contacts the inclined surfaces on the connecting block 51, the inclined surfaces enable the fixing block 52 to slide between the two connecting blocks 51 to achieve splicing, thereby reducing the number of manual intervention calibrations. Inclined blocks 53 are fixedly provided above both sides of the fixing block 52. The inclined blocks 53 are fixedly connected to the plug ring 42. The inclined blocks 53 match the inclined surfaces. The inclined blocks 53 include but are not limited to triangular prism shapes. The inclined blocks 53 contact the inclined surfaces on the connecting block 51.

[0036] The friction coating includes but is not limited to a polyurethane-based wear-resistant lubricating coating. The exteriors of the connecting cylinder 31, the mounting ring 33, the fixing ring 41, the plug-in ring 42, the No. 1 guide ring 43, the No. 2 guide ring 44, the connecting block 51, the fixing block 52, and the bevel block 53 are all coated with a polyurethane-based wear-resistant lubricating coating. The thickness of the polyurethane-based wear-resistant lubricating coating is 200-250 μm. The polyurethane-based wear-resistant lubricating coating provides lubrication and chemical corrosion resistance to the surfaces of the components.

[0037] Lubrication can reduce the friction of the plug-in ring 42 when it contacts the connecting groove 32 and slides into the connecting groove 32 through chamfering, thereby avoiding wear caused by direct contact between components, providing corrosion resistance for the components, and increasing the service life. In addition, the polyurethane-based wear-resistant lubricating coating has a certain elasticity and can fill the gap between the connecting component 3 and the plug-in component 4, so that the connecting component 3 and the plug-in component 4 fit tightly.

[0038] like Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, an exhaust groove 34 is provided at the top of the mounting ring 33. When the plug-in ring 42 slides into the interior of the connecting groove 32, the polyurethane-based wear-resistant lubricating coating brings sealing and tight fit, which will cause the plug-in ring 42 to compress the gas inside the connecting groove 32 when it continues to enter the interior of the connecting groove 32. At this time, the gas can enter the exhaust groove 34 to prevent the gas from affecting the installation. A discharge port 36 is provided on one side of the connecting cylinder 31. The discharge port 36 is communicated with the interior of the connecting groove 32. An exhaust channel 35 is provided at the bottom end of the exhaust groove 34. The gas entering the exhaust groove 34 is discharged to the outside through the exhaust channel 35 and the exhaust port 36. The interior of the exhaust channel 35 is communicated with the interior of the discharge port 36.

[0039] During the assembly process, water can be poured into the exhaust groove 34 to check the state of the water flow inside the exhaust groove 34 and whether it can be discharged normally through the exhaust channel 35 and the outlet 36. In this way, the vertical state of the No. 1 tower 1 can be judged and further tested to make timely adjustments. After the construction is completed, the connection groove 32 can be prevented from accumulating seawater or rainwater to avoid the accumulation of seawater or rainwater and the failure of the coating.

[0040] The exhaust passage 35 and the exhaust port 36 are arranged at an inclination, and the inclination enables the water flow to be discharged to the outside smoothly.

[0041] Example 2

[0042] The tower connection structure provided in Example 1 that is easy to install is further optimized. Specifically, Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, one side of the connecting block 51 is provided with a mounting groove 86 that is connected to the other side of the connecting block 51. A gear 85 is rotatably provided inside the mounting groove 86. A connecting shaft 71 is fixedly provided on the side of the gear 85 near the center of the connecting cylinder 31. The end of the connecting shaft 71 passes through the connecting block 51 and the connecting cylinder 31 and extends to the interior of the connecting cylinder 31. A mounting plate 72 is fixedly provided on the end of the connecting shaft 71. A handle 73 is provided above the mounting plate 72 away from the side of the connecting shaft 71. The connection between the connecting shaft 71 and the handle 73 can be a rotating connection or a fixed connection. Hold the handle 73 and rotate it to make the mounting plate 72 and the connecting shaft 71 drive the gear 85 to rotate.

[0043] The two sides of the gear 85 are respectively provided with a No. 1 locking block 81 and a No. 2 locking block 82 which are slidably connected to the inside of the installation groove 86. The No. 1 locking block 81 and the No. 2 locking block 82 are provided with an inclined surface on the upper side away from the gear 85, and can be spliced with the inclined surface on the connecting block 51. The No. 1 locking block 81 and the No. 2 locking block 82 slide outward synchronously and enter the locking groove 87 on the side of the adjacent fixed block 52 and the inclined block 53, thereby fixing the fixed block 52 and the inclined block 53 in the connecting groove 32. There is no need to use multiple large bolts to be inserted in sequence and then fixed with nuts. It is only necessary to directly rotate the connecting shaft 71 to fix it through the No. 1 locking block 81 and the No. 2 locking block 82. In addition, the rotation stroke of the connecting shaft 71 is short, which improves the speed of installation and fixing.

[0044] The bottom end of the gear 85 is meshed with a second rack 84 fixedly connected to the second locking block 82, and the top end of the gear 85 is meshed with a first rack 83 fixedly connected to the first locking block 81. The first rack 83 and the second rack 84 are both slidably connected to the inside of the mounting groove 86. When the gear 85 rotates, it meshes with the second rack 84 and the first rack 83, driving the second rack 84 and the first rack 83 to move to the sides respectively, thereby driving the second locking block 82 and the first rack 83 to move closer to or away from each other. Locking grooves 87 are provided on both sides of the fixed block 52 and the side of the inclined block 53 away from the fixed block 52. The locking grooves 87 on the inclined block 53 are internally communicated with the locking grooves 87 on the same side of the fixed block 52, so as to increase the contact area with the second locking block 82 or the first locking block 81;

[0045] The connection between each two towers is connected through the connecting component 3, the plug-in component 4 and the sliding component 5, and then fixed with the locking component 8. During the installation process, a platform will be fixed above the inside of the No. 1 tower 1 and the No. 2 tower 2. This platform is located below the connecting tube 31 to facilitate the staff to stand on the platform to control the handle 73 to drive the installation disk 72 to rotate. A clamping device fixedly installed on the platform is provided at the bottom end of the installation disk 72. When the installation disk 72 is controlled to rotate, the No. 1 lock block 81 and the No. 2 lock block 82 are moved outward. After the fixation is completed, the control clamping device clamps and fixes the installation disk 72 to prevent the installation disk 72 from rotating accidentally.

[0046] Example 3

[0047] The tower connection structure provided in Example 1 that is easy to install is further optimized, such as Figure 7As shown, a plurality of No. 2 connecting holes 62 are provided on the fixing block 52, and both ends of the No. 2 connecting holes 62 are in contact with the inner wall of the connecting groove 32. Both ends of the No. 2 connecting holes 62 are provided with No. 1 connecting holes 61 provided on the connecting tube 31. The interior of the No. 2 connecting holes 62 on the fixing block 52 is communicated with the interior of the No. 1 connecting hole 61 on the connecting tube 31. The No. 1 connecting hole 61 close to the inner side of the connecting tube 31 extends to communicate with the interior of the connecting tube 31, and the No. 1 connecting hole 61 located on the outer side extends to communicate with the outer side of the connecting tube 31. The bolt used for fixing is inserted through the No. 1 connecting hole 61, passes through the No. 2 connecting hole 62 and the No. 1 connecting hole 61 on the other side, and extends to the other side of the connecting tube 31, and then is connected with the nut and the bolt to complete the fixation.

[0048] When the fixing ring 41 slides into the interior of the connecting groove 32, and the fixing block 52 passes through the inclined surfaces on both sides of the connecting block 51, several fixing blocks 52 and several connecting blocks 51 are spliced together, so that the No. 2 connecting hole 62 on the fixing block 52 is automatically aligned and connected with the No. 1 connecting hole 61 on the connecting tube 31, thereby reducing manual intervention and adjustment; the connection between each two towers is connected through the connecting component 3, the plug-in component 4 and the sliding component 5, and then fixed with bolts. During the installation process, a platform will be fixed above the interior of the No. 1 tower 1 and the No. 2 tower 2. This platform is located below the connecting tube 31 to facilitate users to stand on the platform to install bolts.

[0049] The use process of the tower connection structure provided by the utility model which is easy to install is as follows:

[0050] When it is necessary to connect the second tower 2 with the first tower 1, the second tower 2 is lifted by the crane, so that the plug ring 42 at the bottom end of the second tower 2 gradually approaches the connecting tube 31, and the plug ring 42 contacts the chamfer at the upper edge of the connecting groove 32. At this time, the second tower 2 continues to move downward, so that the plug ring 42 slides into the inside of the connecting groove 32 through the chamfer, so that the fixed block 52 contacts the connecting block 51. It is necessary to adjust the rotation angle. When the fixed block 52 contacts the inclined surface above the connecting block 51, the fixed block 52 is slid between multiple connecting blocks 51 through the inclined surface, so that several connecting blocks 51 and the fixed block 52 are spliced, and the inclined block 53 contacts the inclined surface on the connecting block 51. The No. 1 guide ring 43 and the No. 2 guide ring 44 contact the two chamfers above the connecting groove 32. During the process, the gap after contact is filled with a polyurethane-based wear-resistant lubricating coating to make the connection tighter.

[0051] When the solution of Example 2 is used, the handle 73 is gripped and rotated, so that the mounting plate 72 and the connecting shaft 71 drive the gear 85 to rotate, and through engagement with the second rack 84 and the first rack 83, the second rack 84 and the first rack 83 are driven to move to the sides respectively, driving the second locking block 82 and the first rack 83 to slide outward synchronously and enter the locking groove 87 on the side of the adjacent fixed block 52 and the inclined block 53, thereby fixing the fixed block 52 and the inclined block 53 in the connecting groove 32, and then controlling the clamping device to clamp and fix the mounting plate 72 to prevent the mounting plate 72 from rotating accidentally;

[0052] Next, if the solution of Example 3 is used, after the connecting blocks 51 and the fixing blocks 52 are assembled, the No. 2 connecting hole 62 on the fixing block 52 is connected to the No. 1 connecting hole 61 on the connecting tube 31. Then, a bolt is inserted through the No. 1 connecting hole 61 on one side, through the No. 2 connecting hole 62 and the No. 1 connecting hole 61 on the other side, and extends to the other side of the connecting tube 31. Then, a nut is threadedly connected to the bolt and tightened.

[0053] When the plug-in ring 42 slides into the connecting groove 32, the plug-in ring 42 compresses the gas inside the connecting groove 32. At this time, the gas is discharged through the exhaust groove 34, the exhaust channel 35 and the exhaust port 36. At the same time, the exhaust groove 34 can prevent seawater or rainwater from accumulating inside the connecting groove 32.
