Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection devices, in particular to a state monitor for lightning protection devices. Background Art

[0002] A lightning protection device refers to the sum of a lightning rod, down conductor, grounding device, surge protector (SPD) and other connecting conductors. The lightning protection device consisting of a lightning rod, down conductor and grounding device is an external lightning protection device, that is, a traditional lightning protection device.

[0003] The lightning arresters in the external lightning protection device include lightning rods, lightning conductors, lightning strips and lightning nets. When in use, the lightning arresters will guide lightning to the ground through down conductors (although the name of down conductors contains wires, they are essentially metal rods) to achieve the purpose of consuming lightning;

[0004] Taking the lightning rod as an example, the lightning rod is usually connected to multiple down conductors. After lightning hits the lightning rod, the lightning will be conducted along the lightning rod, down conductor and grounding device. During this process, there is electrical energy inside the lightning rod and down conductor. In order to monitor the lightning protection effect, a lightning protection detection recorder is usually installed at the lightning rod. The recorder can record data such as the time, frequency and size of the lightning energy received, which is convenient for monitoring the use of the lightning rod and timely discovering when the lightning rod is damaged;

[0005] However, the above-mentioned recorder can only monitor the lightning rod. A single down conductor will have a diversion effect on lightning. During this process, the lightning data flowing inside the down conductor is not monitored. When the down conductor is damaged, the overall lightning-attracting effect will be weakened and even the lightning rod will fail. Therefore, a status monitor of a lightning protection device is proposed to solve the above-mentioned problems. Utility Model Content

[0006] Based on the above description, the utility model provides a status monitor for a lightning protection device to solve the problem that the existing lightning protection detection recorder cannot monitor the down conductor.

[0007] The utility model solves the above-mentioned technical problem through the following technical solution: A status monitor for a lightning protection device, comprising: a protective shell, and an induction coil arranged inside the protective shell, a connecting piece comprising a base frame, a support rod, a top frame, a vertical block, a steering connector and a transverse connector, the steering connector and the transverse connector are arranged inside the vertical block and connected to the induction coil, and a protective block is arranged at the top of the protective shell.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the protective shell includes a shell, the shell is a semi-cylindrical block, the outer surface of the shell is provided with positioning ears, and the bottom end of the shell is provided with a threaded hole.

[0010] Furthermore, the induction coil includes an arc-shaped cable, and a metal joint is provided on a side of the arc-shaped cable close to the vertical block.

[0011] Furthermore, a support rod, a top frame and a vertical block are sequentially arranged at the top of the base frame from bottom to top, and the top frame is arranged at the bottom end of the shell by screws.

[0012] Furthermore, the vertical block is arranged between the shells, and the steering connector and the transverse connector are arranged inside the vertical block.

[0013] Furthermore, the induction coil, the steering connector and the transverse connector are connected to each other, and the three form a complete coil.

[0014] Furthermore, the transverse connector includes a transverse joint, and transverse connection blind holes are provided at both ends of the transverse joint, and the metal joint is adapted to the transverse connection blind holes.

[0015] Furthermore, the steering connector includes a metal connector, which is an L-shaped metal block. Steering connection blind holes are provided at both ends of the metal connector, and the metal joint is adapted to the steering connection blind holes.

[0016] Furthermore, the protection block comprises a protection top block, the bottom end of which is provided with a protection vertical plate and a positioning column, and the positioning column extends to the inside of the positioning ear.

[0017] Furthermore, the protective vertical plate is in contact with the connecting member and the protective shell, and an inserting hole is provided on the outer surface of the protective vertical plate, and the inserting hole corresponds to the steering connection blind hole.

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0033] See also Figure 1-Figure 3 , a state monitor for a lightning protection device, comprising:

[0034] A protective housing 1, wherein the protective housing 1 comprises a shell 11, wherein the shell 11 is a semi-cylindrical block, wherein a positioning ear 12 is disposed on the outer surface of the shell 11, and a threaded hole is disposed at the bottom end of the shell 11; and

[0035] An induction coil 2 is disposed inside the protective housing 1 , and the induction coil 2 includes an arc-shaped cable 21 , and a metal joint 22 is disposed on one side of the arc-shaped cable 21 close to the vertical block 34 ;

[0036] Based on the above, when in use, the two-stage protective shell 1 can be directly mounted on the outside of the down conductor, so that the induction coil 2 is also mounted on the outside of the down conductor. After the down conductor is set, the device can still be installed, which increases the practicality of the device.

[0037] like Figure 1 , Figure 2 , Figure 4-Figure 6 As shown, the connecting member 3 includes a bottom frame 31, a support rod 32, a top frame 33, a vertical block 34, a steering connector 35 and a transverse connector 36, wherein:

[0038] The top of the bottom frame 31 is provided with a support rod 32, a top frame 33 and a vertical block 34 in order from bottom to top. The top frame 33 is set at the bottom end of the shell 11 by screws. The vertical block 34 is set between the shells 11. The steering connector 35 and the transverse connector 36 are set inside the vertical block 34.

[0039] The steering connector 35 and the transverse connector 36 are both arranged inside the vertical block 34 and connected to the induction coil 2. The transverse connector 36 includes a transverse connector 361. Both ends of the transverse connector 361 are provided with transverse connection blind holes 362. The metal connector 22 is adapted to the transverse connection blind holes 362. The steering connector 35 includes a metal connector 351. The metal connector 351 is an L-shaped metal block. Both ends of the metal connector 351 are provided with steering connection blind holes 352. The metal connector 22 is adapted to the steering connection blind holes 352.

[0040] The induction coil 2, the steering connector 35 and the transverse connector 36 are connected to each other, and the three constitute a complete coil;

[0041] Based on the above, the setting of the base frame 31, the support rod 32 and the top frame 33 plays the role of supporting the vertical block 34, so that the connecting piece 3 can fix the protective shell 1 by means of screws. During the fixing process of the protective shell 1, the metal joint 22 is inserted into the interior of the steering connector 35 and the transverse connector 36. In this process, the complete coil composed of the induction coil 2, the steering connector 35 and the transverse connector 36 is sleeved on the outside of the down conductor. Through the setting of the steering connector 35, the coil can be connected to the lightning protection detection recorder through a cable. When connecting, only one end of the cable needs to be inserted into the interior of the steering connection blind hole 352.

[0042] like Figure 1 , Figure 2 as well as Figure 7 As shown, a protective block 4 is arranged at the top of the protective housing 1, the protective block 4 includes a protective top block 41, the bottom end of the protective top block 41 is provided with a protective vertical plate 42 and a positioning column 43, the positioning column 43 extends to the inside of the positioning ear 12, the protective vertical plate 42 is in contact with the connecting member 3 and the protective housing 1, and the outer surface of the protective vertical plate 42 is provided with a plug hole 44, and the plug hole 44 corresponds to the connecting blind hole 352;

[0043] Based on the above, the setting of the protection block 4 plays a role in waterproofing and moisture-proofing, and the protective top block 41 prevents rainwater from directly contacting the protective shell 1 when dripping. Through the two-stage design, the protection block 4 can be directly installed, which increases the convenience during installation, and the gap at the connection of the two sections of the protection block 4 is in a misaligned state with the gap between the connector 3 and the protective shell 1, thereby preventing rainwater from penetrating into the interior of the device through the gap. The vertical gap between the connector 3 and the protective shell 1 is sealed by the protective vertical plate 42, further increasing the waterproof ability of the device.

[0044] In actual use, the utility model can be sleeved on the outside of the installed down conductor by setting the protective shell 1 and the induction coil 2. During the installation process, the metal joints 22 at both ends of the induction coil 2 are respectively inserted into the inside of the transverse connection blind hole 362 and the steering connection blind hole 352. At this time, the above three form a complete coil, which is sleeved on the outside of the down conductor;

[0045] The top frame 33 is connected to the two protective shells 1 by screws, so as to achieve a mutually fixed effect. After the cable and the steering connection blind hole 352 are connected to each other, they are connected to the lightning protection detection recorder (hereinafter referred to as the recorder), so that when the lightning is transmitted through the down conductor, an induced current is generated in the coil, and the current is transmitted to the recorder for recording;

[0046] By setting the positioning ears 12, the protection block 4 can be fixed by inserting the positioning column 43 into the positioning ears 12. The fixed protection block 4 can protect the device. The protective top block 41 prevents rainwater from directly contacting the protective shell 1 when dripping. The gap at the connection between the two sections of the protection block 4 and the gap between the connector 3 and the protective shell 1 are in a misaligned state, thereby preventing rainwater from penetrating into the device through the gap. The vertical gap between the connector 3 and the protective shell 1 is sealed by the protective vertical plate 42, further increasing the waterproof ability of the device.

[0047] The device can be directly installed when facing the installed lightning protection device, including the down conductor that is not easy to disassemble. The installed coil is set on the outside of the down conductor. When lightning strikes the lightning rod or lightning strip and other structures, the lightning is transmitted to the earth through the down conductor. In this process, the size and frequency of the lightning diverted by the down conductor can be transmitted to the recorder. The state of the down conductor can be judged by the data in the recorder. For example, when the current diverted by the down conductor connected to the same lightning rod is different, the conductivity of the smaller down conductor is reduced. If the reduction is too large, maintenance or replacement is required;

[0048] This makes up for the defect that the existing lightning protection equipment lacks equipment for monitoring the state of the down conductor.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
