Description

Technical Field

[0001] The present invention relates to the technical field of lightning protection, and in particular to a lightning protection device applied to a high-altitude system. Background Art

[0002] Buildings in high-altitude areas, due to their height and prominent position, are more likely to be targeted by lightning. The high voltage and instantaneous energy of lightning can directly strike outdoor equipment and buildings, causing exterior wall peeling, equipment damage, and even fires, seriously threatening the integrity and safety of building equipment and structures. Therefore, effective lightning protection measures can significantly reduce this risk and prevent damage.

[0003] Building codes in many countries and regions require that high-altitude buildings be equipped with lightning protection devices, such as lightning rods, to ensure the safety of the building, its equipment, and the people within. Lightning protection is not only an essential part of building lightning protection design but also a key component of building acceptance and safety inspections.

[0004] However, the current lightning protection devices simply install lightning rods around buildings. However, this method of installing lightning rods can only provide protection at fixed locations and cannot actively protect external equipment, resulting in its protection effect and range being very limited. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the current lightning protection device is fixed in position and cannot actively protect external equipment, resulting in its protection effect and range being very limited.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a lightning protection device applied to a high-altitude system, comprising a longitudinal column, a first lifting strut axially fixed inside the longitudinal column, the extended end of the first lifting strut axially fixed to the top limit seat of the humidity sensor installed on the top, a second lifting strut installed inside the extended end of the first lifting strut, an arc-shaped external flip bracket cover movably mounted on the outer side of the extended end of the first lifting strut, an overhead extended lightning rod axially fixed to the top end of the extended end of the second lifting strut, and an external control connecting rod for controlling the arc-shaped external flip support cover movably mounted on the side wall of the extended end of the second lifting strut.

[0007] The first lifting strut includes a first telescopic guide cylinder axially fixed in the opening at the upper end of the longitudinal column, a first externally threaded lifting tube slidably installed inside the first telescopic guide cylinder, a first annular motor installed on the inner wall of the first telescopic guide cylinder, and a first internally threaded adjustment ring installed at the internal control end of the first annular motor.

[0008] The second lifting strut includes a second telescopic guide cylinder axially fixed inside the first externally threaded lifting tube, a second externally threaded lifting tube slidably installed inside the second telescopic guide cylinder, a second annular motor installed on the inner wall of the second telescopic guide cylinder, and a second internally threaded adjustment ring at the internal control end of the second annular motor.

[0009] The top extension lightning rod is axially fixed to the top end of the second externally threaded lifting tube, and the top end of the top limiting seat is provided with a top telescopic through hole matched with the top extension lightning rod.

[0010] An inner limiting guide block is provided on the inner side wall of the first telescopic guide cylinder and the second telescopic guide cylinder, and a strip-shaped limiting guide groove matching the inner limiting guide block is provided on the outer thread surface of the first externally threaded lifting tube and the second externally threaded lifting tube.

[0011] The lower surface of the top limit seat is fixedly equipped with a bottom side bracket that matches the arc-shaped external flip bracket cover. The arc-shaped external flip bracket cover is inserted into the bottom side bracket through the inner assembly shaft and movably assembled with the top limit seat.

[0012] An inner extension cover is slidably mounted on the inner arc surface of the arc-shaped outer flip bracket cover.

[0013] A strip-shaped transition hole matching the external control connecting rod is provided on the outer side surface of the first externally threaded lifting tube.

[0014] An infrared positioning module is fixedly mounted on the end of the inner extension cover.

[0015] The second externally threaded lifting tube is internally fixed with a built-in grounding wire whose bottom end is grounded.

[0016] The beneficial effects of the present invention are:

[0017] (1) The lightning protection device for high-altitude systems of the present invention adopts a two-stage threaded lifting mechanism design, which can automatically control the extension according to changes in the external environment, thereby actively protecting high-altitude buildings and equipment and increasing the protection range;

[0020] (4) An overhead extension lightning rod is axially fixed to the top of the extended end of the second lifting strut, and an external control link is movably mounted on the side wall of the extended end of the second lifting strut.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0029] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] Figure 1 、 Figure 2 、 Figure 3 and Figure 4The lightning protection device shown is used in a high-altitude system, including a longitudinal column 1, a first lifting strut 2 is axially fixed inside the longitudinal column 1, the extended end of the first lifting strut 2 is axially fixed to the top limit seat 4 of the humidity sensor 3 installed on the top, the extended end of the first lifting strut 2 is installed inside the second lifting strut 5, the extended end of the first lifting strut 2 is movably equipped with an arc-shaped external flip support cover 6 on the outside, the extended end of the second lifting strut 5 is axially fixed to the top of the extended end of the second lifting strut 5, and the extended end of the second lifting strut 5 is movably equipped with an external control link 8 for controlling the arc-shaped external flip support cover 6.

[0031] Adjustment principle: When thunderstorm occurs, the humidity in the air increases, and the humidity sensor 3 on the top of the top limit seat 4 senses that the air humidity has decreased. At this time, the humidity sensor 3 will first control the lifting, and the bottom of the arc-shaped external flip bracket cover 6 will be separated from the limit groove at the upper opening position of the longitudinal column 1, and then the second lifting support rod 5 will be controlled to lift the second lifting support rod 5 to control the top extended lightning rod 7 to extend out of the top limit seat 4, and at the same time, the external control connecting rod 8 will be controlled to squeeze outward, and the arc-shaped external flip bracket cover 6 will be controlled to flip outward to form a shielding cover above the protective equipment, which can expand the area of ​​lightning induction and block a certain degree of rain.

[0032] In order to cooperate with the internal telescopic adjustment, the first lifting strut 2 includes a first telescopic guide cylinder 21 axially fixed in the opening at the upper end of the longitudinal column 1, a first externally threaded lifting tube 22 slidably installed inside the first telescopic guide cylinder 21, a first annular motor 23 installed on the inner wall of the first telescopic guide cylinder 21, and a first internally threaded adjustment ring 24 installed at the internal control end of the first annular motor 23.

[0033] The first ring-shaped motor 23 drives the first internally threaded adjustment ring 24 to rotate, thereby controlling the lifting and lowering adjustment of the first externally threaded lifting tube 22 .

[0034] In order to cooperate with the internal telescopic adjustment, the second lifting support rod 5 includes a second telescopic guide cylinder 51 axially fixed inside the first externally threaded lifting tube 22, a second externally threaded lifting tube 52 slidably installed inside the second telescopic guide cylinder 51, a second annular motor 53 installed on the inner wall of the second telescopic guide cylinder 51, and a second internally threaded adjustment ring 54 at the internal control end of the second annular motor 53.

[0035] The second ring motor 53 drives the second internally threaded adjustment ring 54 to rotate, thereby controlling the lifting and lowering adjustment of the second externally threaded lifting tube 52 .

[0036] In order to cooperate with axial assembly and telescopic movement, the top extension lightning rod 7 is axially fixed to the top of the second externally threaded lifting tube 52 , and a top telescopic through hole cooperating with the top extension lightning rod 7 is opened at the top of the top limit seat 4 .

[0037] In order to limit the rotation of the first externally threaded lifting tube 22 and the second externally threaded lifting tube 52, an inner limit guide block 9 is provided on the inner wall of the first telescopic guide cylinder 21 and the second telescopic guide cylinder 51, and a strip-shaped limit guide groove 10 that cooperates with the inner limit guide block 9 is provided on the outer threaded surface of the first externally threaded lifting tube 22 and the second externally threaded lifting tube 52.

[0038] The inner limiting guide block 9 is inserted into the strip-shaped limiting guide groove 10, thereby limiting the rotation of the first externally threaded lifting tube 22 and the second externally threaded lifting tube 52 so that they can only be lifted vertically.

[0039] In order to cooperate with the movable installation, the lower surface of the top limit seat 4 is fixedly equipped with a bottom side bracket that matches the arc-shaped external flip bracket cover 6. The arc-shaped external flip bracket cover 6 is inserted into the bottom side bracket through the inner assembly axis and movably assembled with the top limit seat 4.

[0040] In order to increase the protection area, an inner extension cover 11 is slidably mounted on the inner curved surface of the curved outer flip bracket cover 6 .

[0041] Horizontal guide rails are symmetrically arranged on both sides of the lower end of the arc-shaped external flip bracket cover 6. The inner extension cover 11 is inserted into the horizontal guide rail through the internal threaded translation blocks at both ends and is assembled with the electric control screw thread inside it. The inner extension cover 11 is driven to slide and adjust along the horizontal guide rail by rotating the electric control screw.

[0042] In order to cooperate with the flip transition, a strip-shaped transition hole 12 that cooperates with the external control connecting rod 8 is opened on the outer surface of the first external thread lifting tube 22.

[0043] The external control link 8 passes through the strip-shaped transition hole 12 and is movably assembled with the inner side of the arc-shaped external flip bracket cover 6 .

[0044] In order to improve the extension accuracy, an infrared positioning module 13 is fixedly mounted on the end of the inner extension cover 11 .

[0045] The infrared positioning module 13 automatically controls the flip angle of the arc-shaped external flip bracket cover 6 and the extension length of the inner extension cover 11 by monitoring the position of the device below. Once the infrared positioning module 13 cannot monitor the device below, it controls the inner extension cover 11 to stop extending.

[0046] In order to quickly guide the lightning into the ground, the second externally threaded lifting tube 52 is fixedly assembled with a built-in grounding wire 14 with its bottom end grounded.

[0047] When the second externally threaded lifting tube 52 is lifted, the built-in grounding wire 14 is in a straightened state, thereby increasing the gap between the built-in grounding wire 14 and the inner wall of the vertical column 1, thereby improving safety.

[0048] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
