[0029] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0030] The following refers to Figures 1-3 The tower drum segment with heating function and the wind power tower drum according to the embodiments of the present application are described.

[0031] As Figures 1-3 shown, the tower drum segment with heating function according to the embodiments of the present application comprises a segment body 1 and a heating band 2.

[0032] The segment body 1 has splicing surfaces 11 at both circumferential ends, and at least one splicing surface 11 is paved with the heating band 2. As Figure 1 shown, the segment body 1 is preferably but not limited to an arc-shaped segment around the vertical direction, the axial direction of the segment body 1 is the vertical direction, the circumferential direction of the segment body 1 is the direction around the vertical direction, the radial direction of the segment body 1 is the thickness direction of the segment body 1, the segment body 1 has splicing surfaces 11 at both circumferential ends, the splicing surfaces 11 are used to be connected with the corresponding splicing surfaces 11 of another segment body 1, and among the splicing surfaces 11 at both circumferential ends of the segment body 1, only one splicing surface 11 can be paved with the heating band 2, or both splicing surfaces 11 can be paved with the heating band 2.

[0033] The heating band 2 is provided with an avoiding space 21, the avoiding space 21 is used for a connecting member (not shown in the figure) to pass through, and the connecting member is used to connect two segment bodies 1. As Figure 2 and Figure 3 shown, the heating band 2 is provided with an avoiding space 21, the avoiding space 21 is used for a connecting member such as a reinforcing bar, a bolt or the like to pass through, so that the connecting member can connect one segment body 1 with another segment body 1.

[0034] During the construction of tower tube segments with heating function, at least two tower tube segments need to be connected sequentially in a vertical direction to form a cylindrical tower tube section. When connecting adjacent tower tube segments, one splicing surface 11 of the tube body 1 of one tower tube segment is set opposite to the corresponding splicing surface 11 of the tube body 1 of the other tower tube segment. Only one splicing surface 11 of the two opposite splicing surfaces 11 may be equipped with a heating band 2, or both splicing surfaces 11 may be equipped with a heating band 2. First, the two opposite splicing surfaces 11 are connected by multiple connectors. Then, adhesive materials such as mortar and epoxy adhesive are poured between the two opposite splicing surfaces 11. In working environments such as early morning, night, and winter, the heating band 2 operates and generates heat to raise and maintain the temperature of the adhesive material, thereby ensuring that the adhesive material can solidify smoothly and fix the two tube body segments 1, while achieving the required strength.

[0035] This utility model discloses a tower tube segment with heating function. At least one splicing surface of the segment body is covered with a heating strip. The heating strip generates heat to raise the temperature of the adhesive material, thereby ensuring that the adhesive material maintains a suitable temperature in low-temperature environments, allowing it to solidify smoothly and reach the required strength. The heating strip has clearance spaces for connectors to pass through. This avoids interference between the connectors and the heating strip, ensuring smooth installation of both. Furthermore, it ensures the heating strip is evenly distributed on the splicing surface, guaranteeing uniform temperature of the adhesive material and thus ensuring effective solidification.

[0036] In some embodiments, the splicing surface 11 extends along the axial direction of the tube body 1, the heating band 2 extends along the axial direction of the tube body 1 from one end of the splicing surface 11 to the other end, and the clearance space 21 is provided on both sides of the tube body 1 along the thickness direction with portions of the heating band 2. The clearance space 21 is a strip extending along the axial direction of the tube body 1 from one end of the splicing surface 11 to the other end, or there are multiple clearance spaces 21, and the multiple clearance spaces 21 are arranged at intervals along the axial direction of the tube body 1.

[0037] like Figures 1-3 As shown, the splicing surface 11 is a strip extending in the vertical direction.

[0038] The heating band 2 is a strip extending vertically from the top end of the splicing surface 11 to the bottom end of the splicing surface 11, so as to cover the splicing surface 11 to the maximum extent in the vertical direction, thereby ensuring the temperature uniformity of the adhesive material in the axial direction of the tube body 1.

[0039] The clearance space 21 is a strip extending vertically from the top end of the heating band 2 to the bottom end of the heating band 2. Multiple connectors used to connect the two opposite splicing surfaces 11 pass through the clearance space 21.

[0040] Heating bands 2 are provided on both the left and right sides of the clearance space 21. Therefore, the end of the splicing surface 11 facing the inner circumference of the tube body 1 and the end facing the outer circumference of the tube body 1 both have heating bands 2 that extend continuously in the vertical direction, thereby ensuring the temperature uniformity of the adhesive material in the thickness direction of the tube body 1.

[0041] Understandably, in some embodiments, multiple clearance spaces are provided. These clearance spaces can be rectangular, circular, etc., and are arranged at intervals along the vertical direction. The connectors are correspondingly positioned within the clearance spaces to pass through them. In this case, the adhesive material between adjacent connectors also comes into contact with the heating band, thereby improving the temperature uniformity of the adhesive material. However, a strip-shaped heating band with clearance spaces is easier to process and lay.

[0042] In some embodiments, the heating band 2 includes a wiring portion 22 extending from the splicing surface 11. The wiring portion 22 is used to connect to a power supply device. The wiring portions 22 are two that are spaced apart along the axial direction of the tube body 1, or the wiring portions 22 are two that are spaced apart along the thickness direction of the tube body 1.

[0043] like Figure 2 and Figure 3 As shown, the heating band 2 includes a wiring portion 22 extending from the splicing surface 11; in other words, the wiring portion 22 extends beyond the splicing surface 11. The wiring portion 22 is used to connect a power supply device, which supplies power to the heating band 2 to generate heat.

[0044] In such Figure 2 In the example shown, two terminals 22 are arranged at intervals along the thickness direction of the tube body 1, with one terminal 22 serving as the positive terminal and the other terminal 22 serving as the negative terminal.

[0045] In such Figure 3 In the example shown, two terminals 22 are arranged vertically at intervals, with one terminal 22 serving as the positive terminal and the other terminal 22 serving as the negative terminal.

[0046] The wiring portion 22 extends beyond the splicing surface 11 to prevent the wiring portion 22 from being cast into the adhesive material, and facilitates connection to the power supply equipment when connecting adjacent tower segments, as well as facilitates disconnection from the power supply equipment after connecting adjacent tower segments.

[0047] In some embodiments, the connector includes a reinforcing bar disposed at one circumferential end of the segment body 1. The reinforcing bar protrudes from the splicing surface 11 at one circumferential end of the segment body 1. Multiple reinforcing bars are arranged at intervals along the axial direction of the segment body 1. An insulating layer is provided on the surface of the reinforcing bar. Multiple insertion holes 12 and heating band 2 are provided on the splicing surface 11 at the other circumferential end of the segment body 1. The multiple insertion holes 12 are all opposite to the clearance space 21. The multiple insertion holes 12 are arranged at intervals along the axial direction of the segment body 1. The insertion holes 12 are used to insert the corresponding reinforcing bar of another segment body 1.

[0048] like Figures 1-3 As shown, the segment body 1 has a left end splicing surface 11 and a right end splicing surface 11. The left end splicing surface 11 is provided with a plurality of insertion holes 12 arranged at intervals along the vertical direction, and the right end splicing surface 11 is provided with a plurality of mounting holes 17 arranged at intervals along the vertical direction. The plurality of insertion holes 12 and the plurality of mounting holes 17 are correspondingly arranged. The mounting holes 17 are used to insert and connect one end of the insertion rod. One end of the insertion rod is preferably, but not limited to, connected to the inner wall surface of the mounting hole 17 by a thread. The insertion holes 12 are used to insert the other end of the insertion rod.

[0049] When connecting adjacent tower tube segments, one of the two splicing surfaces 11 arranged opposite each other has multiple mounting holes 17 and the other splicing surface 11 has multiple insertion holes 12. First, a corresponding insertion rod is set in each mounting hole 17. One end of the insertion rod is connected to the corresponding mounting hole 17, and the other end of the insertion rod extends out from the splicing surface 11 where it is set. Then, the two tower tube segments are brought close together so that the two splicing surfaces 11 arranged opposite each other are brought close together, and the other end of each insertion rod is inserted into the corresponding insertion hole 12 of the other splicing surface 11, so that the insertion rod acts as a connector to connect the two tube segments 1.

[0050] It is understood that the segment body is not limited to having mounting holes on one of the splicing surfaces, and the inserts are not limited to being installed on the corresponding splicing surfaces by inserting into the mounting holes. In other embodiments, one end of the insert is cast into the segment body during casting, and the other end of the insert extends from one splicing surface of the segment body, with multiple insertion holes provided on the other splicing surface of the segment body. In other words, the tower segment also includes a connector, one end of which is cast into the segment body, and the other end of which extends from one splicing surface of the segment body. The connector preferably includes, but is not limited to, inserts.

[0051] The surface of the insertion rod is provided with an insulating layer, which can be an insulating coating applied to the surface of the insertion rod or an insulating tape wrapped around the surface of the insertion rod, so as to prevent short circuits caused by contact between the heating band 2 and the insertion rod when the heating band 2 generates heat through power.

[0052] like Figure 2 and Figure 3As shown, the left end splicing surface 11 of the tube body 1 is provided with a heating band 2, and the multiple insertion holes 12 are opposite to the clearance space 21 so that the insertion rod can be inserted into the insertion hole 12.

[0053] The heating strip 2 is more convenient to lay and install on the left end splicing surface 11 with multiple insertion holes 12 than on the right end splicing surface 11 with insertion bars.

[0054] It is understood that the heating band 2 is not limited to being provided on the splicing surface 11 with multiple insertion holes 12. In the embodiment where the reinforcing bar is installed by casting, the heating band 2 is preferably provided on the splicing surface 11 with multiple insertion holes 12. In the embodiment where the reinforcing bar is installed by mounting holes 17, the heating band 2 can be provided on the splicing surface 11 with multiple insertion holes 12 or on the splicing surface 11 with multiple mounting holes 17.

[0055] In some embodiments, the heating band 2 includes a first segment 23, a second segment 24, and a third segment 25. The first segment 23 and the second segment 24 both extend along the axial direction of the tube body 1 and are spaced apart along the thickness direction of the tube body 1. The third segment 25 is located at one end of the splicing surface 11 along the axial direction of the tube body 1. The third segment 25 extends along the thickness direction of the tube body 1 and connects one end of the first segment 23 and one end of the second segment 24. A clearance space 21 is formed between the first segment 23, the second segment 24, and the third segment 25.

[0056] In such Figure 2 In the example shown, the heating band 2 includes a first segment 23, a second segment 24, and a third segment 25. The first segment 23 and the second segment 24 both extend vertically and are spaced apart along the thickness direction of the tube body 1. The first segment 23 is located at one end of the splicing surface 11 facing the outer peripheral surface of the tube body 1, and the second segment 24 is located at one end of the splicing surface 11 facing the inner peripheral surface of the tube body 1. The third segment 25 extends along the thickness direction of the tube body 1 and is preferably, but not limited to, connected between the lower end of the first segment 23 and the lower end of the second segment 24. The first segment 23, the third segment 25, and the second segment 24 are connected in a U-shape. A clearance space 21 is formed between the first segment 23, the second segment 24, and the third segment 25. The clearance space 21 is open between the upper end of the first segment 23 and the upper end of the second segment 24. Multiple sockets 12 are located between the first segment 23 and the second segment 24.

[0057] When the heating band 2 is energized and generates heat, the current flows sequentially along the first segment 23, the third segment 25, and the second segment 24, or sequentially along the second segment 24, the third segment 25, and the first segment 23. The first segment 23 and the second segment 24 are arranged at intervals along the thickness direction of the tube body 1 so that the heating band 2 covers the splicing surface 11 to the maximum extent in the thickness direction of the tube body 1, thereby ensuring uniform temperature of the adhesive material.

[0058] It is understood that in embodiments where the heating strip is located on another splicing surface, multiple inserts and / or multiple mounting holes are located between the first and second segments.

[0059] In some embodiments, the end of the first segment 23 that is different from the end connecting the third segment 25 and the end of the second segment 24 that is different from the end connecting the third segment 25 both extend from the splicing surface 11 to form a wiring portion 22 for connecting power supply equipment.

[0060] In such Figure 2 In the example shown, the upper ends of the first segment 23 and the second segment 24 both extend from the splicing surface 11. In other words, the upper ends of the first segment 23 and the second segment 24 both extend beyond the splicing surface 11, thus forming the wiring portion 22 respectively.

[0061] In some embodiments, the other end of the first segment 23 and the other end of the second segment 24 both extend out of the splicing surface 11 along the axial direction of the segment body 1.

[0062] In such Figure 2 In the example shown, the upper ends of the first segment 23 and the second segment 24 both extend vertically upwards to the outside of the splicing surface 11 to form the connection part 22 respectively.

[0063] It is understood that the upper ends of the first and second segments are not limited to extending from the splicing surface along the axial direction of the segment body. In other embodiments, the upper ends of the first and second segments extend from the splicing surface along the thickness direction of the segment body; in other words, the upper ends of the first and second segments are L-shaped. For example, the upper end of the first segment extends from the outer circumferential surface of the segment body, and the upper end of the second segment extends from the inner circumferential surface of the segment body. Another example is that the upper end of the first segment is higher than the upper end of the second segment, and both the upper ends of the first and second segments extend from the inner circumferential surface of the segment body.

[0064] In some embodiments, the heating band 2 further includes a fourth segment 26, which is located at the other end of the splicing surface 11 along the axial direction of the tube body 1. The fourth segment 26 extends along the thickness direction of the tube body 1 and connects the other end of the first segment 23 and the other end of the second segment 24. An avoidance space 21 is formed between the first segment 23, the second segment 24, the third segment 25 and the fourth segment 26.

[0065] In such Figure 3In the example shown, the heating band 2 further includes a fourth segment 26, which extends along the thickness direction of the tube body 1 and preferably, but not limited to, connects the upper end of the first segment 23 and the upper end of the second segment 24. The fourth segment 26 and the third segment 25 are arranged at intervals in the vertical direction. The first segment 23, the third segment 25, the second segment 24, and the fourth segment 26 are cyclically connected to form a rectangular ring, and a closed clearance space 21 is formed between the first segment 23, the second segment 24, the third segment 25, and the fourth segment 26. Multiple sockets 12 are located between the first segment 23 and the second segment 24, and simultaneously between the third segment 25 and the fourth segment 26.

[0066] When the heating band 2 is energized to generate heat, the current can flow simultaneously from the third segment 25 to the fourth segment 26 along the first segment 23 and the second segment 24, or simultaneously from the fourth segment 26 to the third segment 25 along the first segment 23 and the second segment 24, or simultaneously from the first segment 23 to the second segment 24 along the third segment 25 and the fourth segment 26, or simultaneously from the second segment 24 to the first segment 23 along the first segment 23 and the second segment 24.

[0067] It is understood that in embodiments where the heating strip is located on another splicing surface, multiple inserts and / or multiple mounting holes are located between the first and second segments and between the third and fourth segments.

[0068] In some embodiments, the third segment 25 and the fourth segment 26 both extend from the splicing surface 11 to form a wiring portion 22 for connecting power supply equipment.

[0069] In such Figure 3 In the example shown, the third segment 25 and the fourth segment 26 both extend from the splicing surface 11, thereby forming the wiring portion 22 respectively.

[0070] When the heating band 2 is energized and generates heat, the current first reaches one of the third segment 25 and the fourth segment 26, and then simultaneously flows along the first segment 23 and the second segment 24 to the other of the third segment 25 and the fourth segment 26.

[0071] It is understood that in other embodiments, the first and second segments may also be configured to extend from the splicing surface to form a connection portion, for example, the first and second segments may extend at one end in the vertical direction, or at the middle of the first and second segments in the vertical direction.

[0072] In some embodiments, the third segment 25 and the fourth segment 26 both extend out of the splicing surface 11 along the thickness direction of the segment body 1, and the wiring portion 22 formed by the third segment 25 and the wiring portion 22 formed by the fourth segment 26 are located on the same side of the splicing surface 11 along the thickness direction of the segment body 1.

[0073] In such Figure 3In the example shown, the third segment 25 and the fourth segment 26 extend along the thickness direction of the segment body 1 and protrude from the splicing surface 11 at one end adjacent to the inner circumferential surface of the segment body 1, thereby forming a wiring portion 22 respectively. Therefore, the wiring portion 22 formed by the third segment 25 and the wiring portion 22 formed by the fourth segment 26 both protrude from the inner circumferential surface of the segment body 1, so that the operator can connect the power supply equipment in the space surrounded by the two tower segments to be connected.

[0074] It is understood that, in other embodiments, the wiring portion formed in the third segment and the wiring portion formed in the fourth segment may both protrude from the outer peripheral surface of the segment body.

[0075] It is understood that the third and fourth segments are not limited to extending from the splicing surface along the thickness direction of the segment body. In other embodiments, the third segment extends upward from the middle of the splicing surface along the thickness direction of the segment body, and the fourth segment extends to the left or right of the splicing surface.

[0076] In some embodiments, the heating band 2 is a carbon fiber mesh belt. This allows the heating band 2 to heat up rapidly, achieving high heat conversion efficiency and saving power consumption. Simultaneously, the carbon fiber mesh belt generates low current and does not produce electromagnetic radiation when generating heat, thus ensuring high safety for operators. Furthermore, because the carbon fiber mesh belt is lightweight, flexible, heat-resistant, and has high tensile strength, it is also easy to lay and install.

[0077] The preferred mesh size of the carbon fiber mesh belt is 3mm to 8mm, and more preferably 5mm.

[0078] In some embodiments, at least one splicing surface 11 is provided with an adhesive layer, which is used to bond the heating band 2.

[0079] Specifically, the splicing surface 11 where the heating band 2 is laid is provided with an adhesive layer. The heating band 2 is laid on the adhesive layer so that the heating band 2 is bonded and fixed to the splicing surface 11 through the adhesive layer to prevent the heating band 2 from moving.

[0080] The material of the adhesive layer is preferably, but not limited to, the same as the adhesive material, and more preferably, mortar, epoxy adhesive, etc.

[0081] In some embodiments, each splicing surface 11 is provided with a plurality of grout-receiving grooves 13, which are arranged at intervals along the axial direction of the segment body 1. The splicing surface 11 at one circumferential end of the segment body 1 is also provided with a grouting groove 14, which forms a grouting port 15 at one end of the segment body 1 in the thickness direction. The splicing surface 11 at the other circumferential end of the segment body 1 is provided with a heating band 2, and the plurality of grout-receiving grooves 13 at the other circumferential end of the segment body 1 are all opposite to the clearance space 21.

[0082] like Figure 2 and Figure 3As shown, each splicing surface 11 is provided with multiple slurry-containing grooves 13, and the multiple slurry-containing grooves 13 on the same splicing surface 11 are arranged at intervals along the vertical direction.

[0083] The splicing surface 11 at one circumferential end of the segment body 1 is also provided with a grouting groove 14, preferably but not limited to a splicing surface 11 with mounting holes 17 and / or inserts for the segment body 1 (e.g., Figure 2 and Figure 3 The right end splicing surface 11 is shown.

[0084] One end of the grouting groove 14 along the thickness direction of the segment body 1 forms a grouting port 15. The grouting port 15 is preferably, but not limited to, formed on the outer peripheral surface of the segment body 1. The other end of the grouting groove 14 along the thickness direction of the segment body 1 is arranged vertically at intervals with the grout-containing groove 13 on the right end splicing surface 11. It is preferably, but not limited to, located below the multiple grout-containing grooves 13 on the right end splicing surface 11 and located at the bottom of the right end splicing surface 11.

[0085] The heating band 2 is located on the splicing surface 11 at the other end of the segment body 1 in the circumferential direction. In other words, the heating band 2 is located on the splicing surface 11 of the segment body 1 where the grouting groove 14 is not provided (e.g., Figure 2 and Figure 3 As shown in the left end splicing surface 11), the multiple slurry grooves 13 on the left end splicing surface 11 are all opposite to the clearance space 21. In other words, the heating band 2 is set on the outer periphery of the multiple slurry grooves 13.

[0086] When connecting adjacent tower segments, the two opposite splicing surfaces 11 are first connected by multiple connectors. Then, adhesive materials such as mortar and epoxy adhesive are injected between the two opposite splicing surfaces 11 through the grouting port 15. The adhesive material will form a protrusion at the other end of the grouting groove 14 and in the grout receiving groove 13, thereby increasing the contact area between the adhesive material and the splicing surface 11, thereby enhancing the connection strength of the two opposite splicing surfaces 11.

[0087] The heating band 2 is set on the outer periphery of multiple grout grooves 13 to ensure that after the adhesive material is poured between two oppositely arranged splicing surfaces 11, the heating band 2 uniformly heats the adhesive material in all the grout grooves 13 on the other end of the grout groove 14 and on the two splicing surfaces 11, so that the adhesive material between the two oppositely arranged splicing surfaces 11 has a high temperature uniformity, thereby ensuring the solidification effect of the adhesive material.

[0088] In some embodiments, each splicing surface 11 is provided with two docking portions 16 arranged at intervals along the thickness direction of the tube body 1. The docking portions 16 extend along the axial direction of the tube body 1 and are used to directly or indirectly dock with the corresponding docking portion 16 of another tube body 1. On the splicing surface 11 provided with the heating band 2, the heating band 2 is located between the two docking portions 16.

[0089] like Figure 2 and Figure 3 As shown, each splicing surface 11 is provided with two docking parts 16 arranged at intervals along the thickness direction of the tube body 1, and each docking part 16 extends in the vertical direction.

[0090] The docking part 16 is preferably, but not limited to, a docking groove that penetrates the tube body 1 in a vertical direction. When connecting adjacent tower tubes, in the two splicing surfaces 11 that are arranged opposite each other, the two docking grooves of one splicing surface 11 are arranged opposite to the two docking grooves of the other splicing surface 11. Then, a docking rod is inserted between the two opposite docking grooves. The docking rod is also embedded in the two opposite docking grooves so that the two docking grooves are indirectly connected by the docking rod, thereby positioning the two splicing surfaces 11 that are arranged opposite each other by the docking rod and the docking groove.

[0091] On the splicing surface 11 where the heating band 2 is provided (e.g. Figure 2 and Figure 3 As shown in the left end splicing surface 11), the heating band 2 is located between the two mating parts 16 to avoid touching the heating band 2 during the mating process and causing damage to the heating band 2. At the same time, it also avoids the mating parts 16 being located in the clearance space, which would affect the temperature transmission of the heating band 2 and thus affect the temperature uniformity and solidification effect of the adhesive material.

[0092] It is understood that the docking part is not limited to the docking groove that is indirectly connected through the docking rod. In some other embodiments, the docking part on one splicing surface of the tube segment body is a boss, and the docking part on the other splicing surface is a groove. When adjacent tower tube segments are connected, in the two splicing surfaces that are set opposite each other, the boss on one splicing surface is connected to the groove on the other splicing surface to achieve direct docking.

[0096] Preferably, in the plurality of tower tube sections, all tower tube sections are made of at least two tower tube segments connected together, or, except for the topmost steel tower tube section, the remaining tower tube sections are made of at least two tower tube segments connected together.
