Detailed implementation manners

[0030] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] Since the implementation of the national standard "Technical Specification for Inspection of Lightning Protection Devices of Buildings" GB / T 21431-2015 edition, it has provided a basis for inspection for units carrying out lightning protection device inspection work, enabling the inspection work to be carried out more standardly, playing a positive role in promoting the level of lightning protection inspection technology. At the same time, it has played a positive role in improving the lightning protection and disaster reduction work of the whole society, ensuring the safety of the lives and property of the country, society and people, and having great social benefits.

[0032] However, since this standard was issued in September 2015 and implemented on April 1, 2016, more than 7 years have passed. During these 7 years, the development of lightning protection technology at home and abroad has been very rapid, and new lightning protection device inspection and testing technologies and means have emerged. In order to further standardize the lightning protection device inspection and testing technology and adapt to the development of lightning protection technology, this standard is revised.

[0033] Therefore, through the joint efforts of the compilation group and experts from relevant fields such as meteorology, architectural design institutes, electric power, railways, scientific research institutions, universities and inspection units for more than two years, it was finally compiled and completed.

[0034] It was officially approved and issued by the State Administration for Market Regulation and the National Standardization Administration on December 28, 2023, and will be officially implemented on July 1, 2024. This standard is a comprehensive revision of GB / T 21431-2015. This revision fully absorbs the domestic and foreign lightning protection device inspection and testing technologies and management experiences, and refers to and draws on the latest technical achievements of lightning defense.

[0035] The revised standard is more scientific and reasonable, and has an important guiding role in promoting the development of China's lightning protection and disaster reduction cause, constructing a perfect and reasonable lightning protection system, and improving the lightning protection device inspection ability.

[0036] In the related art, the measurement and inspection items of the lightning protection device include measuring the specifications of the grounding wire diameter, the surge protector wire diameter, the main equipotential bar in the computer room, and the main equipotential bar in the distribution room to ensure compliance with the lightning protection specifications and technical requirements. However, there are many wire diameter specifications to be detected in the lightning protection device, and the measurement process is cumbersome and time-consuming.

[0037] To solve the above technical problems, please refer to Figure 1 and Figure 2 A lightning protection device detection auxiliary measuring instrument provided by the present application includes a first function board 1 and a plurality of measuring parts 2. A plurality of first sliding grooves 11 are arranged at intervals on the first function board 1, and a plurality of first sliding grooves 11 all extend to the edge of the first function board 1. A plurality of measuring parts 2 can be respectively slidably arranged in a plurality of first sliding grooves 11, and a first end 201 of each measuring part 2 has a measuring groove 21. The measuring part 2 can be switched between a measuring position and a retracted position. Among them, when the measuring part 2 is in the measuring position, the first end 201 of the measuring part 2 can extend out of the first sliding groove 11, and the measuring groove 21 can be used to measure the object to be measured 6. When the measuring part 2 is in the retracted position, the first end 201 of the measuring part 2 can retract into the first sliding groove 11.

[0038] Optionally, the shape of the first function board 1 can be a square board, a circular board, a polygonal board, etc., and no specific limitation is made here. Here, the first function board 1 is taken as an example of a square board for description, and the overall size specification of the first function board 1 is 110mm * 70mm. A plurality of first sliding grooves 11 can be arranged at intervals along a first direction on the side surface of the first function board 1, and a plurality of first sliding grooves 11 can all extend to the edge of the first function board 1 along a second direction. The second direction can intersect with the first direction. That is to say, a plurality of first sliding grooves 11 are arranged close to the same side edge of the first function board 1, and a plurality of first sliding grooves 11 all extend to the same edge of the first function board 1.

[0039] A plurality of measuring parts 2 can be respectively slidably arranged in a plurality of first sliding grooves 11, so that each measuring part 2 can move relative to a corresponding first sliding groove 11. That is to say, the measuring part 2 can extend relative to the first sliding groove 11 to the measuring position, or retract relative to the first sliding groove 11 to the retracted position. A first end 201 of each measuring part 2 has a measuring groove 21. It should be noted that when the measuring part 2 is in the retracted position, the first end 201 of the measuring part 2 is the end close to the edge of the first function board 1. That is, when the measuring part 2 is in the measuring position, the first end 201 of the measuring part 2 extends out of the first sliding groove 11, and when measuring, when in the retracted position, the first end 201 of the measuring part 2 retracts into the first sliding groove 11.

[0040] Multiple measuring grooves 21 have different width dimensions. The dimension of the measuring groove 21 in the first direction is the width dimension, and the width dimension of each measuring groove 21 corresponds to a standard dimension, which can be set according to national standards. The state has regulations on the wire diameters of different wire harnesses inside the lightning protection device and the specification dimensions of different equipotential bars. When measuring different objects to be measured 6 inside the lightning protection device, here taking the object to be measured 6 as a wire harness as an example, the corresponding measuring member 2 can be moved to the measuring position according to the wire harness specification to be measured, and the measuring groove 21 is matched with the corresponding wire harness for measurement. After measurement, the measuring member 2 can be moved to the retracted position. Therefore, only by pushing out the corresponding measuring member 2 according to the wire harness specification to be measured, the wire diameter of the wire harness can be measured, and it can be directly judged whether the wire harness meets the national standards, and the lightning protection detection work can be completed more accurately and conveniently.

[0041] In some embodiments, the first functional board 1 can have six first sliding grooves 11, and six different measuring members 2 can be respectively slidably arranged in the six first sliding grooves 11. The first ends 201 of the six measuring members 2 all have a measuring groove 21, and along the first direction, the notch width dimensions of the six measuring grooves 21 are 9.3 mm, 7.5 mm, 5.3 mm, 4.4 mm, 3.9 mm, and 3.4 mm in sequence. The gap between two adjacent measuring members 2 is 5 mm. Along the second direction, the lengths of the three measuring members 2 with notch width dimensions of 9.3 mm, 7.5 mm, and 5.3 mm of the measuring groove 21 are all 35 mm, and the maximum lengths of these three measuring members 2 protruding from the first sliding groove 11 are all 30 mm. The lengths of the three measuring members 2 with notch width dimensions of 4.4 mm, 3.9 mm, and 3.4 mm of the measuring groove 21 are all 25 mm, and the maximum lengths of these three measuring members 2 protruding from the first sliding groove 11 are all 20 mm.

[0043] Optionally, when the measuring member 2 is in the measuring position, the end of the measuring member 2 located in the first sliding groove 11 is the second end 202, and the boss 22 can protrude outward from the surface of the measuring member 2, and the boss 22 can protrude from the first sliding groove 11, so that a boss 22 similar to an operating rod can be formed on the measuring member 2, which can facilitate people to push and pull the measuring member 2 with their fingers and can easily switch the measuring member 2 between the measuring position and the retracted position.

[0044] Preferably, the boss 22 can be a circular boss 22, the diameter of the boss 22 is 2 mm, and the boss 22 is located at the middle position of the measuring member 2.

[0045] Please refer to Figure 1 and Figure 2 In some embodiments, the first functional board 1 further has a second chute 12. The second chute 12 can be arranged at intervals with a plurality of first chutes 11. The lightning protection device detection auxiliary measuring instrument further includes a measuring ruler 3. The measuring ruler 3 is slidably arranged in the second chute 12, and the measuring ruler 3 can stretch relative to the first functional board 1 along the second chute 12.

[0046] Optionally, the second chute 12 can extend along the first direction, and one end of the second chute 12 can also extend to the edge of the first functional board 1. The second chute 12 and the plurality of first chutes 11 are arranged at intervals along the second direction. The measuring ruler 3 is slidably arranged in the second chute 12, so that the measuring ruler 3 is equivalent to a telescopic caliper. Preferably, the measuring range of the measuring ruler 3 is 80 mm. When the size of the object to be measured 6 exceeds the measuring range of the measuring groove 21, the measuring ruler 3 can be used to measure the object to be measured 6, so that the object to be measured 6 with a larger size range can be measured.

[0047] Optionally, a boss 22 can also be provided on the measuring ruler 3 to facilitate the movement of the measuring ruler 3.

[0048] Combined with Figure 1 and Figure 2 In some embodiments, a first clamping member 13 can be provided on the side of the first functional board 1. One end of the measuring ruler 3 outside the second chute 12 can be provided with a second clamping member 31. The first clamping member 13 and the second clamping member 31 are arranged opposite to each other. The lengths of both the first clamping member 13 and the second clamping member 31 are 15 mm. The first clamping member 13 and the second clamping member 31 can be used to clamp the object to be measured 6. By fixing the object to be measured 6 with the first clamping member 13 and the second clamping member 31 and performing measurement, the measurement accuracy can be increased.

[0049] Please refer to Figure 1 and Figure 3 In some embodiments, the second chute 12 and the plurality of first chutes 11 can be located on the same side of the first functional board 1.

[0050] Optionally, the first functional board 1 can have a first side and a second side arranged opposite to each other. The second chute 12 and the plurality of first chutes 11 can be arranged on the first side, so that a plurality of measuring members 2 and the measuring ruler 3 can be arranged on the same side, which is convenient for measurement. In addition, a cable common value comparison table can be printed on the second side, which is convenient for people to judge whether the measured cable meets the standard according to the comparison table.

[0051] Please refer to Figure 1 and Figure 4 In some embodiments, the width of the open end of the first chute 11 is smaller than the width of the bottom surface of the first chute 11.

[0052] Optionally, the dimension of the first sliding groove 11 in the first direction is the width dimension of the first sliding groove 11. When the width of the open end of the first sliding groove 11 is smaller than the width of the groove bottom surface of the first sliding groove 11, the formed first sliding groove 11 is a trapezoidal groove, that is, a part of the cross-section of the first sliding groove 11 is trapezoidal. Thus, when the measuring member 2 is slidably disposed in the first sliding groove 11, the measuring member 2 can be prevented from falling off from the open end of the first sliding groove 11.

[0053] Specifically, the width of the open end of the first sliding groove 11 is 14 mm, the width of the groove bottom surface of the first sliding groove 11 is 15.6 mm, the depth of the first sliding groove 11 is 1.5 mm, and the included angle formed by the inner side surface and the groove bottom surface of the first sliding groove 11 is 59°, so that a trapezoidal groove can be formed.

[0054] Please refer to Figure 4 , in some embodiments, a relief groove 111 is recessed in the groove bottom surface of the first sliding groove 11. The relief groove 111 extends in the same direction as the first sliding groove 11, and a step structure 112 is formed between the relief groove 111 and the first sliding groove 11. The measuring member 2 is slidably disposed on the step structure 112.

[0055] Optionally, another relief groove 111 can be provided on the groove bottom surface of the first sliding groove 11. The width dimension of the relief groove 111 in the first direction is smaller than the width dimension of the groove bottom surface of the first sliding groove 11, so that a step structure 112 can be formed between the relief groove 111 and the first sliding groove 11. When the measuring member 2 is disposed in the first sliding groove 11, the step structure 112 can provide support for the measuring member 2, and the contact area between the measuring member 2 and the first sliding groove 11 can be reduced. Thus, the friction between the measuring member 2 and the first sliding groove 11 can be reduced, and the measuring member 2 can be moved more easily along the first sliding groove 11.

[0058] A magnifying glass 42 with a diameter of Ф50 is installed in the middle of the second functional board 4. When the magnifying glass 42 is needed, the second functional board 4 can be rotated relative to the first functional board 1 until the first functional board 1 and the second functional board 4 do not interfere with each other, that is, the first functional board 1 does not block the position of the magnifying glass 42. The magnifying glass 42 can be used to check the parameters and functional status of the surge protector.

[0059] Please refer to Figure 5 and Figure 6 , in some embodiments, a card slot 43 is provided on the side of the second functional board 4, and the card slot 43 can be used to measure the object to be measured 6.

[0060] Optionally, a card slot 43 can be provided on each of the opposite sides of the second functional board 4, and the card slot 43 can be used to measure the specifications of the isopotential bonding strip made of copper or steel in the computer room. For the convenience of description, the opposite sides of the second functional board 4 are defined as the upper side and the lower side. The upper side of the second functional board 4 is provided with a card slot 43 with a depth of 40mm * 4mm, and the lower side of the second functional board 4 is provided with a card slot 43 with a depth of 30mm * 3mm. Through the two different specifications of card slots 43, different specifications of isopotential bonding strips in the computer room can be measured.

[0061] Please refer to Figure 5 and Figure 6 , in some embodiments, the lightning protection device detection auxiliary measuring device can include an LED lamp 5, and the LED lamp 5 can be movably connected to the second functional board 4.
