Description

Technical Field

[0001] This application relates to the field of lightning protection equipment technology, and in particular to a lightning protection detection auxiliary rod. Background Technology

[0002] In lightning protection systems, lightning rods are a common and important protective device. A lightning rod generally consists of an air terminal (needle), a conductor, and a grounding electrode. Lightning is attracted by the air terminal, flows through the conductor to the grounding electrode, and is then conducted into the ground. Lightning rods undergo regular inspection and maintenance to ensure their effectiveness in attracting lightning and to prevent potential hazards.

[0003] During testing, voltage is typically supplied to the lightning rod, and current and voltage are measured in designated areas of the duct and in test wells reserved for the grounding electrode to determine the conductivity of the lightning rod.

[0004] However, since lightning arresters are fixed on the top of buildings, they are usually secured with wire clamps and powered by specific equipment. However, some lightning arresters on the top of buildings are installed independently, which is 1m to 2m away from the roof, making wire installation inconvenient. Utility Model Content

[0005] This application provides a lightning protection detection auxiliary rod to solve the problem of inconvenient wiring when powering a lightning arrester.

[0006] This application provides a lightning protection detection auxiliary pole, including a hollow pole body, a conductor, a connecting part, a universal joint, and a support base. A cavity is formed within the hollow pole body, which has a first end and a second end, each with an opening communicating with the cavity. The conductor extends within the cavity, with both ends extending outside the openings at the first and second ends, respectively. The connecting part is fixedly disposed at the first end of the hollow pole body, and has an abutting arc surface and a conductor. At least a portion of the conductor is located at the abutting arc surface, and the conductor is electrically connected to the conductor. The abutting arc surface is used to abut against a lightning arrester. A universal joint is disposed at the second end, with a gap between the universal joint and the opening at the second end. The support base is fixedly connected to the universal joint, and the support base is rotatably connected to the hollow pole body via the universal joint.

[0007] In this application, the wire is installed on a hollow rod. When power is needed for the lightning arrester, power can be supplied to the wire located at the second end. At the same time, by contacting the contact surface with the lightning arrester, the power supply component transfers electrical energy to the lightning arrester through the wire and conductor. The hollow rod can be placed using a universal joint and support base, without direct contact with the lightning arrester, making the power supply process for the lightning arrester more convenient. In addition, the hollow rod can maintain the position of the wire, making the detection process more labor-saving and convenient.

[0008] In some embodiments of this application, the hollow rod includes two end posts and a main body, with the end posts and the main body fixedly connected. The two end posts are located at opposite ends of the main body, forming a first end and a second end, respectively. A universal joint is fixedly mounted on one end post. The two end posts are relatively fixed, which allows the universal joint and the contact portion to remain in a fixed position during the testing process.

[0009] In some embodiments of this application, the main body includes a first sub-rod and a second sub-rod. The inner diameter of the first sub-rod is larger than the outer diameter of the second sub-rod. An internal thread is formed on the inner side of the first sub-rod, and an external thread is formed on the outer wall of the second sub-rod. The first and second sub-rods are threadedly connected. The first and second sub-rods can be rotated through the threaded structure to adjust the length of the main body and the total length of the hollow rod as needed, thereby enabling the auxiliary rod to be used in more detection environments.

[0010] In some embodiments of this application, multiple first and second sub-rods are provided, and the first and second sub-rods are alternately arranged along the axial direction of the hollow rod. Adjacent first and second sub-rods are threadedly connected. Multiple first and second sub-rods allow the length of the main body to be adjusted, while shortening the adjustment interval of each part of the main body and reducing the length of each first and second sub-rod, which helps to reduce the possibility of main body breakage.

[0011] In some embodiments of this application, the main body further includes an annular seat, and an annular seat is fixedly provided in the middle of both the first sub-rod and the second sub-rod; the main body also includes multiple springs, and springs are provided on both sides of each annular seat. The springs are fixedly connected to the annular seat, and the wire is coiled between two adjacent springs located in the first sub-rod and the second sub-rod.

[0012] The ring seat and spring can apply a flexible pressure to the wire located between the two springs, so that when the first and second sub-rods rotate and the distance between the two ring seats moves relatively far apart or close together, the wire can increase or decrease the pitch of the wire disc through the spring, so that the wire can change according to the length of the body.

[0013] In some embodiments of this application, the wire is fixedly connected to the ring seat. This fixed connection prevents the wire from sliding between adjacent ring seats, which could lead to excessive wire accumulation and tangling within one ring seat. This helps improve the stability and smoothness of the wire's state changes when the body length changes.

[0014] In some embodiments of this application, both ends of the second sub-rod are provided with external threads, and the main body also includes two nuts. Each end of the second sub-rod has a nut on its external thread, and the nut can abut against the end face of the first sub-rod. The nuts can restrict the position of the first sub-rod, so that the first sub-rod can be stabilized according to the adjusted position, avoiding relative rotation between the first and second sub-rods due to the shaft-hole fit.

[0015] In some embodiments of this application, the abutting portion includes two abutting arc surfaces, namely a first abutting arc surface and a second abutting arc surface, wherein the radius of the first abutting arc surface is larger than the radius of the second abutting arc surface. The two abutting arc surfaces can be applied to two different lightning rods, thereby expanding the applicability of the auxiliary rod and helping to further improve the convenience of lightning protection equipment detection.

[0016] In some embodiments of this application, the support base includes a connecting plate and multiple support claws, which are circumferentially spaced around the connecting plate and rotatably connected to it. The connecting plate and support claws can be placed on a flat, inclined, or curved surface to adapt to different roof structures and improve the convenience of lightning protection equipment inspection.

[0017] In some embodiments of this application, the lightning protection detection auxiliary rod further includes an insulating sleeve, which is detachably fitted over the first end and the abutment portion. The insulating sleeve can protect the abutment portion, preventing it from accumulating dust or being bumped when not in use, thus affecting its conductivity. Attached Figure Description

[0030] In lightning protection systems, lightning rods are a common and important protective device. A lightning rod generally consists of an air terminal (needle), a conductor, and a grounding electrode. Lightning is attracted by the air terminal, flows through the conductor to the grounding electrode, and is then conducted into the ground. Lightning rods undergo regular inspection and maintenance to ensure their effectiveness in attracting lightning and to prevent potential hazards.

[0031] During testing, voltage is typically supplied to the lightning rod, and current and voltage are measured in designated areas of the duct and in test wells reserved for the grounding electrode to determine the conductivity of the lightning rod.

[0032] However, since lightning arresters are fixed on the top of buildings, they are usually secured with wire clamps and powered by specific equipment. However, some lightning arresters on the top of buildings are installed independently, which is 1m to 2m away from the roof, making wire installation inconvenient.

[0033] Therefore, please refer to Figure 1 This application provides a lightning protection detection auxiliary pole, including a hollow pole body 1, a wire 2, an abutment part 3, a universal joint 4, and a support base 5.

[0034] Please refer to Figure 1 A hollow rod 1 has a cavity 11 formed inside. The hollow rod 1 has a first end 12 and a second end 13, both of which have openings communicating with the cavity 11. The first end 12 and the second end 13 are two opposite ends of the hollow rod 1. The openings can be circular holes, square holes, or other shapes. The openings can be located on the end face of the hollow rod 1 or on the side wall of the hollow rod 1. The two openings can be equal in size or unequal in size.

[0035] Please refer to Figure 1 The hollow rod 1 can be made of metal, such as aluminum alloy or stainless steel, or of non-metallic material, such as high-strength insulating engineering plastic, and is manufactured using injection molding. The hollow rod 1 can be a telescopic rod structure, with telescopic connections via threaded connections, sliding rail connections, or non-fitting relative sliding. The hollow rod 1 can comprise multiple rod sections, which can be fixedly connected, threadedly connected, or connected in other relatively fixed ways.

[0036] Please refer to Figure 1 The length of the hollow rod 1 can be between 1m and 3m. Its length can be designed according to needs, such as an adjustable length of 1.5m to 2.5m, so as to adapt to more different usage environments.

[0037] Please refer to Figure 1 The conductor 2 extends within the cavity 11, with its two ends extending to the openings of the first end 12 and the second end 13, respectively. The conductor 2 can be a copper-based alloy conductor 2, an aluminum-based composite material conductor 2, or a high-temperature superconducting conductor 2. For example, the copper-based alloy conductor 2 can be a copper-silver alloy, a copper-tin alloy, etc. Its alloy properties significantly improve the mechanical strength and fatigue resistance of the conductor 2. In simulated scenarios of instantaneous high voltage and high current such as lightning, it can withstand electromagnetic impacts and is not prone to deformation or breakage, ensuring stable current transmission.

[0038] Please refer to Figure 1 An insulation layer can be provided on the outside of conductor 2 to protect conductor 2 and prevent electric shock to test personnel. For example, the insulation layer can adopt a multi-layer composite structure, with the innermost layer being a polyimide film, the middle layer being a silicone rubber insulation layer, and the outermost layer being a fluoroplastic coating.

[0039] Please refer to Figure 1 Polyimide film has excellent high temperature resistance, which can withstand the high temperature generated by lightning strikes, and also has good electrical insulation properties, which can effectively isolate the conductor 2 from electrical contact with the outside world.

[0040] The silicone rubber insulation layer is soft and elastic, and can adapt to different degrees of bending as the conductor 2 expands and contracts with the rod, making it less prone to cracking and ensuring insulation performance.

[0041] The fluoroplastic coating can resist harsh outdoor environments, such as ultraviolet radiation and chemical corrosion, extending the service life of conductor 2 and ensuring that conductor 2 can safely and stably supply power to the lightning rod's lightning-attracting part in various complex environments.

[0042] Please refer to Figure 1 The abutment portion 3 is fixedly disposed at the first end 12 of the hollow rod body 1. The abutment portion 3 has an abutment arc surface 31 and a conductor 32. The conductor 32 is at least partially located at the abutment arc surface 31 and is electrically connected to the wire 2. The abutment arc surface is used to abut against the lightning arrester. The abutment portion 3 can be fixedly connected to the first end 12. The size of the abutment portion 3 can be larger than the diameter of the hollow rod body 1. The abutment portion 3 can be spherical or hemispherical in shape.

[0043] Please refer to Figure 1The contact part 3 can be made entirely of conductive material, such as aluminum, or copper or alloy. The contact part 3 can also be made of a combination of multiple materials, such as the outer shell being made of plastic and the inner core being made of wire 2, which can achieve the same purpose.

[0044] Please refer to Figure 1 The contact surface 31 of the contact part 3 is concave, and its opening can face the side of the hollow rod 1. The surface can be a circular arc to facilitate contact with the cylindrical lightning arrester. The radius of the arc can be between 12mm and 22mm, preferably 15mm or 18mm.

[0045] Please refer to Figure 1 Universal joint 4 is disposed at the second end 13, and a gap is provided between universal joint 4 and the opening at the second end 13. Universal joint 4 can be a rigid universal joint 4, specifically a cross-type universal joint 4, a double universal joint 4, or a ball cage type universal joint 4, preferably a ball cage type universal joint 4.

[0046] Please refer to Figure 1 The support base 5 is fixedly connected to the universal joint 4, and the support base 5 is rotatably connected to the hollow rod 1 through the universal joint 4. The support base 5 is fixedly connected to the universal joint 4, and the hollow rod 1 is fixedly connected to the universal joint 4. The hollow rod 1 and the support base 5 need to rotate relative to each other. Therefore, the support base 5 and the hollow rod 1 can be fixedly connected to different parts of the universal joint 4 respectively.

[0047] Please refer to Figure 1 For example, taking the ball cage universal joint 4 as an example, the support seat 5 can be connected to the outer ball sleeve of the universal joint 4, and the hollow rod 1 can be fixedly connected to the steel ball inside the ball sleeve.

[0048] Please refer to Figure 1 The support base 5 can be a tripod support structure or a suction cup adsorption support structure.

[0049] Please refer to Figure 1 In this application, the wire 2 is installed on the hollow rod 1. When power is needed for the lightning arrester, power can be supplied to the wire 2 located at the second end 13. At the same time, by contacting the contact surface with the lightning arrester, the power supply component can transfer electrical energy to the lightning arrester through the wire 2 and the conductor 32. The hollow rod 1 can be placed through the universal joint 4 and the support base 5 without directly contacting the lightning arrester, making the power supply process of the lightning arrester more convenient. At the same time, the hollow rod 1 can maintain the position of the wire 2, making the detection process more labor-saving and convenient.

[0050] Please refer to Figure 2In some examples, the hollow rod 1 includes two end posts 14 and a main body 15, which are fixedly connected. The two end posts 14 are located at both ends of the main body 15, forming a first end 12 and a second end 13, respectively. A universal joint 4 is fixedly mounted on one end post 14. The two end posts 14 are relatively fixed, which can fix the position of the universal joint 4 and the abutment part 3 during the testing process.

[0051] Please refer to Figure 2 In some examples, the end post 14 can be a solid structure, and the main body 15 can be a telescopic main body 15, which can be composed of multiple sections. The first end 12 and the second end 13 can refer to the two end posts 14 respectively, or they can refer to only a part of the end post 14; the main body 15 and the end post 14 can be welded or fixed in other ways.

[0052] Please refer to Figure 2 In some examples, the main body 15 includes a first sub-rod 151 and a second sub-rod 152. The inner diameter of the first sub-rod 151 is larger than the outer diameter of the second sub-rod 152. An internal thread 1511 is formed on the inner side of the first sub-rod 151, and an external thread 1521 is formed on the outer wall of the second sub-rod 152. The first sub-rod 151 and the second sub-rod 152 are threadedly connected. The first sub-rod 151 and the second sub-rod 152 can be rotated through the threaded structure to adjust the length of the main body 15 and adjust the total length of the hollow rod 1 as needed, thereby enabling the auxiliary rod to be used in more detection environments.

[0053] In some examples, the first sub-rod 151 and the second sub-rod 152 may have the same thickness, the same length, and the same material. The threads between the first sub-rod 151 and the second sub-rod 152 may be clearance fit to make their rotation smoother.

[0054] Please refer to Figure 2 The depth of the internal thread 1511 of the first sub-rod 151 can be equal to the length of the external thread 1521 of the second sub-rod 152, or the depth of the internal thread 1511 can be slightly greater than the length of the external thread 1521. The length of the internal thread 1511 and the external thread 1521 on the first sub-rod 151 and the second sub-rod 152 can account for 30% to 40% of the length of the first sub-rod 151 and the second sub-rod 152.

[0055] Please refer to Figure 3In some examples, multiple first sub-rods 151 and second sub-rods 152 are provided, and the first sub-rods 151 and second sub-rods 152 are alternately arranged along the axial direction of the hollow rod 1. Adjacent first sub-rods 151 and adjacent second sub-rods 152 are threaded together. Multiple first sub-rods 151 and multiple second sub-rods 152 allow the length of the main body 15 to be adjusted, while shortening the adjustment interval of each part of the main body 15 and shortening the length of each first sub-rod 151 and second sub-rod 152, which helps to reduce the possibility of breakage of the main body 15.

[0056] Please refer to Figure 3 In some examples, the number of first sub-stems 151 can be one more than the number of second sub-stems 152, so that the two end posts 14 are fixedly connected to the two first sub-stems 151 respectively.

[0057] The number of second sub-rods 152 can be 2 to 5, and their number and length can be adjusted as needed.

[0058] Please refer to Figure 4 In some examples, the main body 15 also includes an annular seat 153, and the annular seat 153 is fixedly provided in the middle of the first sub-rod 151 and the second sub-rod 152; the main body 15 also includes a plurality of springs 154, and springs 154 are provided on both sides of each annular seat 153. The springs 154 are fixedly connected to the annular seat 153, and the wire 2 is coiled between two adjacent springs 154 located in the first sub-rod 151 and the second sub-rod 152.

[0059] Please refer to Figure 4 The annular seat 153 and the spring 154 can apply a flexible pressure to the wire 2 located between the two springs 154, so that when the first sub-rod 151 and the second sub-rod 152 rotate and the distance between the two annular seats 153 moves relatively far apart or close together, the wire 2 can increase or decrease the pitch of the wire 2 disc through the springs 154, so that the wire 2 can change according to the length of the body 15.

[0060] Please refer to Figure 4 In some examples, the annular seat 153 is annular and can be fixedly installed in the first sub-rod 151 or the second sub-rod 152 by means of a step. The annular seat 153 and the first sub-rod 151 or the second sub-rod 152 can also be welded together. The spring 154 can be a thrust spring 154, thereby enabling it to provide thrust to the conductor 2.

[0061] Please refer to Figure 4In some examples, the wire 2 is fixedly connected to the ring seat. The fixed connection between the wire 2 and the ring seat can prevent the wire 2 from sliding between two adjacent ring seats, which would cause the wire 2 in one of the ring seats to become too crowded and tangled. This helps to improve the stability and smoothness of the state change of the wire 2 when the length of the body 15 changes.

[0062] Please refer to Figure 4 In some examples, the wire 2 and the corresponding ring seat can be glued or fixed in other ways.

[0063] Please refer to Figure 5 In some examples, both ends of the second sub-rod 152 are provided with external threads 1521, and the main body 15 also includes two nuts 155. Each end of the second sub-rod 152 has a nut 155 on its external thread 1521, and the nut 155 can abut against the end face of the first sub-rod 151. The nut 155 can restrict the position of the first sub-rod 151, so that the first sub-rod 151 can be stabilized according to the adjusted position, avoiding relative rotation between the first sub-rod 151 and the second sub-rod 152 due to the shaft hole fit.

[0064] Please refer to Figure 5 In some examples, the two nuts 155 at the two ends of the second sub-rod 152 can be set to correspond to the two first sub-rods 151 connected to the second sub-rod 152.

[0065] Please refer to Figure 5 When the number of second sub-rods 152 is greater than that of first sub-rods 151, the second sub-rods 152 located at the edge can also be provided with only one set of external threads 1521 and nuts 155, which can achieve the same purpose.

[0066] Please return to the reference. Figure 1 In some examples, the contact portion 3 includes two contact arc surfaces 31, namely a first contact arc surface 31 and a second contact arc surface 31, wherein the radius of the first contact arc surface 31 is larger than the radius of the second contact arc surface 31. The two contact arc surfaces 31 can be used for two different lightning rods, thereby expanding the applicability of the auxiliary rod and helping to further improve the convenience of lightning protection equipment detection.

[0067] In some examples, the two abutting arc surfaces 31 are used to abut against lightning rods of different sizes, and the diameters of the two abutting arc surfaces 31 can be 15mm and 18mm respectively.

[0068] Please continue to refer to Figure 1In some examples, the support base 5 includes a connecting plate 51 and multiple support claws 52, which are circumferentially spaced around the connecting plate 51 and are rotatably connected to the connecting plate 51. The connecting plate 51 and the support claws 52 can be placed on a flat, inclined, or curved surface to adapt to different roof structures and improve the convenience of lightning protection equipment inspection.

[0069] In some examples, the connecting plate 51 can be fixedly connected to the universal joint 4, and the support claw 52 can be rotatably connected to the connecting plate 51 via a hinge. The number of support claws 52 can be 3 to 6.

[0070] Please continue to refer to Figure 1 In some examples, the lightning protection detection auxiliary rod also includes an insulating sleeve 6, which is detachably fitted onto the first end 12 and the abutment portion 3. The insulating sleeve 6 can protect the abutment portion 3 from dust or impact when not in use, thus preventing it from affecting the conductivity.

[0071] In some examples, the insulating sleeve 6 can be a rubber sleeve or made of other materials.

[0072] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0073] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto.
