Description

Technical Field

[0001] This utility model relates to the field of wind power generation, specifically to a tower pipe section with heating function and a wind power tower. Background Technology

[0002] Tower sections are used to stack and form the tower. For concrete tower sections, bonding materials such as mortar or epoxy adhesive need to be poured between adjacent sections during stacking to connect at least two sections and form the tower. The setting speed and strength of the bonding material are affected by temperature. In working environments such as early morning, night, and winter, the bonding material is difficult to set due to low temperatures, and the strength after setting is often insufficient, which limits the construction time of wind turbine towers and affects the construction progress.

The heating strip extends circumferentially along the tube section body to maximize circumferential coverage of the splicing surface. 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 achieve 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.

[0008] In some embodiments, the clearance space is provided with portions of the heating band on both radial sides of the pipe section body. The clearance space is a strip extending circumferentially along the pipe section body.

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The following is for reference. Figure 1 and Figure 2 This invention describes a tower pipe section with heating function and a wind turbine tower according to embodiments of the present invention.

[0032] like Figure 1 and Figure 2 As shown, the tower tube section with heating function in this embodiment of the present invention includes a tube section body 1 and a heating belt 2.

[0033] Both ends of the pipe section body 1 have splicing surfaces 11, and at least one splicing surface 11 is covered with a heating belt 2, which extends circumferentially along the pipe section body 1. Figure 1 and Figure 2 As shown, the pipe section body 1 is preferably, but not limited to, a cylindrical shape along the vertical direction. The axial direction of the pipe section body 1 is vertical, and the radial direction of the pipe section body 1 is the thickness direction. The pipe wall of the pipe section body 1 can be straight or inclined along the vertical direction. In other words, the cross-sectional area of ​​the pipe section body 1 can be constant, decrease, or increase along the vertical direction. The top and bottom end faces of the pipe section body 1 are both splicing surfaces 11, which are used to connect with the corresponding splicing surface 11 of another pipe section body 1. Among the two splicing surfaces 11 of the pipe section body 1, only one splicing surface 11 can be covered with the heating belt 2, or both splicing surfaces 11 can be covered with the heating belt 2. Preferably, but not limited to, the top splicing surface 11 is covered with the heating belt 2.

[0034] The heating band 2 is provided with a clearance space 21, which allows the connecting piece (not shown in the figure) to pass through. Figure 1 and Figure 2 As shown, the heating band 2 is provided with a clearance space 21, which is used for connecting parts such as reinforcing bars, bolts, anchor cables, and hanging nails to pass through.

[0035] During the construction of tower tube sections with heating function, multiple tower tube sections need to be connected sequentially in the vertical direction to form a tower. When connecting adjacent tower tube sections, the bottom splicing surface 11 of the tube body 1 of one tower tube section is set opposite to the top splicing surface 11 of the tube body 1 of another tower tube section. Only one of the two splicing surfaces 11 can be provided with a heating band 2, or both splicing surfaces 11 can be provided with a heating band 2. Preferably, but not limited to, the top splicing surface 11 is provided with a heating band 2. Adhesive materials such as mortar and epoxy adhesive are poured between the two 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 sections 1, while achieving the required strength. The connector can be placed between two pipe sections 1 before the adhesive material is poured between the two relatively set splicing surfaces 11, or it can be placed between the two pipe sections 1 after the adhesive material is poured, or it can be placed inside multiple pipe sections 1 after multiple pipe sections 1 forming the tower are connected by adhesive material.

[0036] This utility model embodiment features a tower tube section with a heating function. At least one splicing surface of the tube section body is covered with a heating strip. The heating strip extends circumferentially along the tube section body to maximize circumferential coverage of the splicing surface. 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 achieve 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.

[0037] In some embodiments, the clearance space 21 is provided with heating bands 2 on both radial sides of the pipe section body 1. The clearance space 21 is a strip extending circumferentially along the pipe section body 1. Alternatively, there are multiple clearance spaces 21, which are arranged at intervals along the circumferential direction of the pipe section body 1.

[0038] like Figure 1 and Figure 2 As shown, the clearance space 21 is a strip extending circumferentially along the pipe section body 1, and multiple connectors used to connect adjacent pipe section bodies 1 pass through the clearance space 21.

[0039] The clearance space 21 has heating bands 2 on both the inner and outer circumferential sides along the radial direction of the pipe section body 1. Therefore, the splicing surface 11 has heating bands 2 extending circumferentially at one end facing the inner circumferential surface of the pipe section body 1 and at one end facing the outer circumferential surface of the pipe section body 1, thereby ensuring the temperature uniformity of the adhesive material in the thickness direction of the pipe section body 1.

[0040] Understandably, in other embodiments, multiple clearance spaces are provided. These clearance spaces can be rectangular, circular, etc., and are arranged at intervals along the circumference of the pipe section body. 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 strip, thereby improving the temperature uniformity of the adhesive material. However, strip-shaped heating strips with clearance spaces are easier to process and lay.

[0041] In some embodiments, the length of the heating band 2 along the circumferential direction of the pipe section body 1 is 95% or more of the length of the splicing surface 11 along the circumferential direction of the pipe section body 1, such as 95%, 98%, etc. This is to maximize the coverage of the splicing surface 11 in the circumferential direction of the pipe section body 1, thereby ensuring the temperature uniformity of the adhesive material in the circumferential direction of the pipe section body 1.

[0042] like Figure 1 and Figure 2 As shown, the two ends of the heating band 2 extending in the direction of extension form notches in the circumference of the pipe section body 1. In other words, the length of the heating band along the circumference of the pipe section body is less than 100% of the length of the splicing surface along the circumference of the pipe section body. This is to avoid short circuits when the heating band 2 is energized and generates heat.

[0043] It is understood that the two ends of the heating band extending in the direction of extension are not limited to forming notches in the circumferential direction. In other embodiments, the two ends of the heating band extending in the direction of extension are arranged side by side in the circumferential direction of the pipe section body and spaced apart along the thickness direction of the pipe section body to avoid short circuits. In this case, the length of the heating band along the circumferential direction of the pipe section body is 100% or more of the length of the splicing surface along the circumferential direction of the pipe section body.

[0044] In some embodiments, the heating belt 2 includes a belt body 22 and a wiring portion 23. The belt body 22 is disposed on the splicing surface 11 and extends circumferentially along the pipe section body 1. The wiring portion 23 is provided at both ends of the extension direction of the belt body 22. The wiring portion 23 extends out of the splicing surface 11 and is used to connect to the power supply equipment.

[0045] like Figure 1 and Figure 2 As shown, the heating band 2 includes a band body 22 and a wiring section 23. The entire band body 22 is disposed on the splicing surface 11 and extends circumferentially along the pipe section body 1 to generate heat to raise the temperature of the adhesive material.

[0046] Both ends of the belt body 22 are provided with a wiring portion 23. One end of the wiring portion 23 is located on the splicing surface 11 and connected to the belt body 22. The other end of the wiring portion 23 extends out of the splicing surface 11. In other words, the other end of the wiring portion 23 extends out of the splicing surface 11.

[0047] The wiring section 23 is used to connect the power supply equipment. Among the wiring sections 23 at both ends of the belt body 22, one wiring section 23 is used as the positive terminal and the other wiring section 23 is used as the negative terminal, so that the power supply equipment supplies power to the heating belt 2, thereby generating heat in the heating belt 2.

[0048] It should be noted that the wiring section 23 can also generate heat.

[0049] The wiring part 23 extends beyond the splicing surface 11 to prevent the wiring part 23 from being cast into the adhesive material, and facilitates connection to the power supply equipment when connecting adjacent tower pipe sections, as well as facilitates disconnection from the power supply equipment after connecting adjacent tower pipe sections.

[0050] In some embodiments, the belt body 22 includes a first belt body 221 and a second belt body 222. Both the first belt body 221 and the second belt body 222 extend circumferentially along the pipe section body 1 and are arranged at radial intervals along the pipe section body 1, forming a clearance space 21 between the first belt body 221 and the second belt body 222.

[0051] In such Figure 1 In the example shown, the belt body 22 includes a first belt body 221 and a second belt body 222. Both the first belt body 221 and the second belt body 222 extend circumferentially along the pipe section body 1 and are arranged side by side and spaced apart along the radial direction of the pipe section body 1. The space between the first belt body 221 and the second belt body 222 forms a clearance space 21.

[0052] The wiring section 23 includes a first wiring section 231 and a second wiring section 232. The first wiring section 231 is located at both ends of the extension direction of the first belt body 221, and the second wiring section 232 is located at both ends of the extension direction of the second belt body 222. The first wiring section 231 is spaced apart from the second belt body 222, and the second wiring section 232 is spaced apart from the first belt body 221. The first wiring section 231 and the second wiring section 232 located at the same end of the extension direction of the heating belt 2 are arranged at intervals.

[0053] In such Figure 1In the example shown, the wiring section 23 includes a first wiring section 231 and a second wiring section 232. The first wiring section 231 is located at both ends of the extension direction of the first belt body 221, and the second wiring section 232 is located at both ends of the extension direction of the second belt body 222. The two first wiring sections 231 and the two second wiring sections 232 are respectively connected to the power supply equipment, so that the first belt body 221 and the second belt body 222 independently generate heat under the action of current. In other words, a portion of the current flows sequentially along the positive first wiring section 231, the first belt body 221, and the negative first wiring section 231 to generate heat in the first belt body 221, and another portion of the current flows sequentially along the positive second wiring section 232, the second belt body 222, and the negative second wiring section 232 to generate heat in the second belt body 222. The on / off state and the duration of the on / off state of both are independently controlled, preferably, but not limited to, being consistent.

[0054] The first tape 221 generates heat at one end of the splicing surface 11 facing the outer circumferential surface of the pipe section body 1, and the second tape 222 generates heat at one end of the splicing surface 11 facing the inner circumferential surface of the pipe section body 1. This ensures that the tape 22 covers the splicing surface 11 to the maximum extent along the thickness direction of the pipe section body 1, thereby ensuring the temperature uniformity of the adhesive material in the thickness direction of the pipe section body 1. Simultaneously, the extension lengths of the first tape 221 and the second tape 222 cover the splicing surface 11 to the maximum extent along the circumference of the pipe section body 1, thus ensuring the temperature uniformity of the adhesive material in the circumferential direction of the pipe section body 1.

[0055] The first wiring section 231 is spaced apart from the second wiring section 232 and the second belt body 222. The second wiring section 232 is also spaced apart from both the first wiring section 231 and the first belt body 221, thereby avoiding short circuits during power supply.

[0056] In some embodiments, the extension length of the first belt body 221 is greater than the extension length of the second belt body 222, and each end of the first belt body 221 is closer to the other end of the second belt body 222 relative to one end of the second belt body 222 located at the same end in the extension direction of the heating belt 2. The second wiring portion 232 extends from the second belt body 222 in a direction away from the first belt body 221, and the first wiring portion 231 extends from the first belt body 221 in a direction from the first belt body 221 toward the second belt body 222.

[0057] In such Figure 1 In the example shown, the first belt body 221 and the second belt body 222 are arranged side by side along the thickness direction of the pipe section body 1. The first belt body 221 is located at the outer peripheral end of the splicing surface 11, and the second belt body 222 is located at the inner peripheral end of the splicing surface 11. The extension length of the first belt body 221 is greater than the extension length of the second belt body 222.

[0058] The front end of the first belt body 221 is located behind the front end of the second belt body 222. The first wiring portion 231 at the front end of the first belt body 221 and the second wiring portion 232 at the front end of the second belt body 222 both extend toward the inside of the pipe section body 1, so that the first wiring portion 231 and the second wiring portion 232 at the front end are spaced apart along the circumference of the pipe section body 1, and the first wiring portion 231 at the front end is prevented from contacting the second belt body 222, and the second wiring portion 232 at the front end is prevented from contacting the first belt body 221.

[0059] The rear end of the first belt body 221 is located in front of the rear end of the second belt body 222. The first wiring portion 231 at the rear end of the first belt body 221 and the second wiring portion 232 at the rear end of the second belt body 222 both extend toward the inside of the pipe section body 1, so that the first wiring portion 231 and the second wiring portion 232 at the rear end are spaced apart along the circumference of the pipe section body 1, and the first wiring portion 231 at the rear end is prevented from contacting the second belt body 222, and the second wiring portion 232 at the rear end is prevented from contacting the first belt body 221.

[0060] Meanwhile, both the first wiring section 231 and the second wiring section 232 extend from the splicing surface 11 into the pipe body 1, which facilitates the connection and disconnection of the power supply equipment by the operator inside the pipe.

[0061] It is understood that the heating belt is not limited to having the first belt body located on the outer periphery of the second belt body. In other embodiments, the first belt body is located on the inner periphery of the splicing surface, the second belt body is located on the outer periphery of the splicing surface, and both the first wiring portion and the second wiring portion extend from the splicing surface to the outside of the pipe of the pipe section body.

[0062] It is understood that the first wiring portion and the second wiring portion are not limited to extending from the same side of the splicing surface along the thickness direction of the pipe section body. In some other embodiments, the first wiring portion connected to the first belt body at the outer peripheral end of the splicing surface extends to the outside of the pipe section body, and the second wiring portion connected to the second belt body at the inner peripheral end of the splicing surface extends to the inside of the pipe section body.

[0063] It should be noted that, since the extension lengths of the first belt body and the second belt body are different, the maximum coverage length of the first belt body, the second belt body, the first wiring portion and the second wiring portion in the circumferential direction of the pipe section body is taken as the length of the heating belt along the circumferential direction of the pipe section body.

[0064] In some embodiments, the belt body 22 includes a first segment 223, a second segment 224, a third segment 225, and a fourth segment 226. The first segment 223 and the second segment 224 both extend along the axial direction of the pipe section body 1 and are arranged at radial intervals along the pipe section body 1. The third segment 225 connects one end of the extension direction of the first segment 223 and one end of the extension direction of the second segment 224. The fourth segment 226 connects the other end of the extension direction of the first segment 223 and the other end of the extension direction of the second segment 224. A clearance space 21 is formed between the first segment 223, the second segment 224, the third segment 225, and the fourth segment 226.

[0065] In such Figure 2 In the example shown, the belt body 22 includes a first segment 223, a second segment 224, a third segment 225 and a fourth segment 226. The first segment 223 and the second segment 224 both extend circumferentially along the pipe section body 1 and are arranged side by side and spaced apart along the thickness direction of the pipe section body 1. The extension lengths of the first segment 223 and the second segment 224 can be the same or have a small difference.

[0066] The third segment 225 and the fourth segment 226 both extend along the thickness direction of the pipe section body 1 and are arranged at intervals along the circumference of the pipe section body 1. The third segment 225 and the fourth segment 226 can be arranged in parallel or at an angle.

[0067] The third segment 225 is connected between the front end of the first segment 223 and the front end of the second segment 224, and the fourth segment 226 is connected between the rear end of the first segment 223 and the rear end of the second segment 224, so that the first segment 223, the second segment 224, the third segment 225 and the fourth segment 226 are connected to form a closed space and serve as a clearance space 21.

[0068] Current can flow from one of the third segment 225 and the fourth segment 226 simultaneously along the first segment 223 and the second segment 224 to the other of the third segment 225 and the fourth segment 226 and generate heat.

[0069] The first segment 223 generates heat at the end of the splicing surface 11 facing the outer circumference of the pipe section body 1, and the second segment 224 generates heat at the end of the splicing surface 11 facing the inner circumference of the pipe section body 1. This allows the belt body 22 to cover the splicing surface 11 to the maximum extent along the thickness direction of the pipe section body 1, thereby ensuring the temperature uniformity of the adhesive material in the thickness direction of the pipe section body 1. At the same time, the extension lengths of the first segment 223 and the second segment 224 cover the splicing surface 11 to the maximum extent along the circumference of the pipe section body 1, thereby ensuring the temperature uniformity of the adhesive material in the circumferential direction of the pipe section body 1.

[0070] In some embodiments, both the third segment 225 and the fourth segment 226 are provided with a wiring portion 23, and the wiring portion 23 connecting the third segment 225 and the wiring portion 23 connecting the fourth segment 226 extend from the splicing surface 11 along the same side of the radial direction of the pipe section body 1.

[0071] In such Figure 2 In the example shown, the third segment 225 and the fourth segment 226 are both provided with a wiring part 23 at one end facing the pipe body 1. The two wiring parts 23 are arranged adjacent to each other and spaced apart along the circumference of the pipe body 1 and extend into the pipe body 1 so that the operator can connect and disconnect the power supply equipment inside the pipe body 1.

[0072] One of the terminals 23 is the positive terminal and the other terminal 23 is the negative terminal. The current is transmitted along the positive terminal terminal 23 to one of the third segment 225 and the fourth segment 226, and then simultaneously along the first segment 223 and the second segment 224 to the other of the third segment 225 and the fourth segment 226, and then transmitted to the negative terminal terminal 23.

[0073] 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.

[0074] The preferred mesh size of the carbon fiber mesh belt is 3mm to 8mm, and more preferably 5mm.

[0075] In some embodiments, at least one splicing surface 11 is provided with an adhesive layer, which is used to bond the heating band 2.

[0076] 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.

[0077] 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.

[0078] In some embodiments, the connectors include splicing connectors for connecting adjacent pipe sections 1 and / or hoisting connectors for connecting hoisting equipment.

[0079] The splicing connectors preferably include, but are not limited to, prestressed anchor cables, prestressed bolts, and reinforcing bars. These connectors are used to connect adjacent pipe sections 1. During the construction of tower pipe sections with heating functions, the splicing connectors can be used to connect two pipe sections 1 before the adhesive material is poured between the two oppositely positioned splicing surfaces 11, or after the adhesive material has been poured. Alternatively, multiple pipe sections 1 forming the tower can be connected together after all sections have been connected with adhesive material.

[0080] The lifting connector is preferably, but not limited to, a lifting spike located at the top of the pipe section body 1. The lifting connector is used to connect the lifting equipment so that the lifting equipment can lift the pipe section body 1. It should be noted that the bottom of the pipe section body 1 is provided with a clearance space for inserting a lifting connector onto another pipe section body 1. When constructing a tower pipe section with a heating function, the lifting connector can be inserted into the corresponding clearance space before the adhesive material is poured between the two oppositely arranged splicing surfaces 11, or it can be inserted into the clearance space after the adhesive material is poured.

[0081] In some embodiments, at least one splicing surface 11 is provided with a plurality of channels 12, which are arranged at intervals along the circumference of the pipe section body 1. The channels 12 are used to insert connectors. On the splicing surface 11 provided with heating band 2, the plurality of channels 12 are opposite to the clearance space 21.

[0082] The connectors can be all splicing connectors, or a combination of splicing connectors and hoisting connectors.

[0083] When prestressed anchor cables are used in the splicing connectors, the duct 12 penetrates the pipe section body 1 along its axial direction, and forms openings on both the top and bottom splicing surfaces 11 of the pipe section body 1 for inserting the prestressed anchor cables. The top splicing surface 11 is provided with a heating band 2, and the openings formed by the duct 12 on the top splicing surface 11 are opposite to the clearance space 21 to facilitate the insertion of the prestressed anchor cables. Multiple ducts 12 are provided, and these ducts 12 are arranged at intervals along the circumference of the pipe section body 1. It is understood that some of the ducts 12 can also serve as clearance spaces for inserting hoisting connectors.

[0084] When prestressed bolts and reinforcing bars are used as splicing connectors, the prestressed bolts and / or reinforcing bars used as splicing connectors are preferably, but not limited to, located on the bottom splicing surface 11 of the pipe section body 1, and extend downward from the bottom splicing surface 11. The top splicing surface 11 of the pipe section body 1 is provided with a channel 12, which is preferably, but not limited to, a blind hole. When adjacent pipe sections body 1 are connected, the connector of the upper pipe section body 1 is inserted into the channel 12 of the lower pipe section body 1. Multiple connectors and channels 12 are provided correspondingly and are arranged at intervals along the circumference of the pipe section body 1. It is understood that some of the channels 12 can also serve as clearance space for inserting hoisting connectors.

[0085] It should be noted that the prestressed bolts and / or reinforcing bars can be cast onto the bottom splicing surface 11 of the pipe section body 1 during manufacturing, or mounting holes can be provided on the bottom splicing surface 11 of the pipe section body 1, with the prestressed bolts and / or reinforcing bars threadedly connected to the mounting holes.

[0086] It is understood that the connectors are not limited to splicing connectors and hoisting connectors. In other embodiments, the connectors can also be positioning connectors such as positioning rods. For example, the pipe section body has multiple channels that pass through it, and the bottom splicing surface of the pipe section body is also provided with a positioning rod. When adjacent pipe sections are connected, the positioning rod of the upper pipe section body is inserted into a part of the channel of the lower pipe section body to position the two pipe sections. The remaining channel is used to install prestressed anchor cables.

[0087] In some embodiments, the interior of the pipe section body 1 has a prestressed corrugated pipe that penetrates the pipe section body 1 along its axial direction. The cavity of the prestressed corrugated pipe forms a channel 12 penetrating the pipe section body 1. An insulating layer is provided at the end of the prestressed corrugated pipe on the splicing surface 11 where the heating band 2 is provided. The splicing connector is a prestressed anchor cable.

[0088] Specifically, the connector is a prestressed anchor cable. The pipe section body 1 has multiple prestressed corrugated pipes. The prestressed corrugated pipes penetrate the pipe section body 1 in a vertical direction. The cavity of the prestressed corrugated pipe forms a channel 12 that penetrates the pipe section body 1. Openings are formed at both the top splicing surface 11 and the bottom splicing surface 11 of the pipe section body 1 for inserting the prestressed anchor cable.

[0089] The top splicing surface 11 is provided with a heating band 2. Each prestressed corrugated pipe has an insulating layer at its top. The insulating layer can be an insulating coating applied to the surface of the top of the prestressed corrugated pipe or an insulating tape wrapped around the top of the prestressed corrugated pipe, so as to prevent short circuits caused by the heating band 2 contacting the prestressed corrugated pipe when it generates heat through power.

[0090] In some embodiments of the present invention, the tower tube section with heating function further includes a pad plate. The splicing surface 11 at the top of the tube section body 1 is provided with a top opening and a heating band 2. The top opening is opposite to the clearance space 21. The top opening is provided with a pad plate, and the surface of the pad plate is provided with an insulating layer.

[0091] Specifically, the top splicing surface 11 of the pipe section body 1 is provided with multiple openings and heating bands 2. The multiple openings are arranged at intervals along the circumference of the pipe section body 1 and are opposite to the clearance space 21. Each opening is provided with a leveling pad. The surface of the pad is provided with an insulating layer. The insulating layer can be an insulating coating applied to the surface of the pad or an insulating tape wrapped around the pad, so as to prevent short circuits caused by contact between the heating band 2 and the pad when it generates heat through power.
