Description

A protective device for lightning protection mechanism of electrical equipment Technical Field

[0001] This utility model relates to the field of lightning rod technology; specifically, this utility model relates to a protective device for a lightning protection mechanism of electrical equipment. Background Technology

[0002] A lightning rod is a device used to protect buildings and other structures from damage caused by lightning strikes. Its core principle is to actively guide the lightning current to safely discharge into the ground, thereby avoiding fires, structural damage or damage to electronic equipment caused by lightning strikes.

[0003] The challenges posed by strong winds to lightning rods are mainly in terms of mechanical reliability and protection effectiveness. In high-rise buildings or in strong winds, some slender lightning rods may bend, sway, or even break under strong winds, leading to protection failure. Long-term high-frequency vibration can cause metal fatigue, accelerate material aging, and increase the risk of breakage. Summary of the Invention

[0004] In view of this, the present invention provides a protective device for lightning protection mechanisms of electrical equipment, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0005] To achieve the aforementioned objectives, this utility model provides a protective device for a lightning protection mechanism of electrical equipment, comprising: a support frame, serving as the base of a lightning rod, which is fixedly installed on a building or metal frame by bolts;

[0006] The main pipe, mounted on the support frame, is used to install the lightning rod;

[0007] An annular fixing plate is fixedly installed between the support frame and the main pipe;

[0008] A wind shield is fitted onto the outer surface of the lightning rod.

[0009] A support structure is installed at the bottom of the air plate. The bottom of the support structure is slidably engaged with an annular fixing plate, and the support structure is in an inclined state.

[0010] In the protective device of the lightning protection mechanism of electrical equipment as described above, the support structure optionally includes: a support tube, the top of which is fixedly connected to the bottom of the wind plate, and the bottom of which abuts against the annular fixing plate. The annular fixing plate is provided with an annular groove, and the bottom of the support tube slides in cooperation with the annular groove.

[0011] In the protective device of the lightning protection mechanism of electrical equipment as described above, the support structure may optionally include: a stop rod, which is slidably sleeved inside the support tube, and the bottom of the stop rod can abut against the annular fixing plate;

[0012] The air inlet is provided on the air panel and is connected to the air inlet. The support pipe is connected to the air inlet.

[0013] The protective device for a lightning protection mechanism of electrical equipment further includes:

[0014] The deflection structure is rotatably mounted inside the air deflector.

[0015] A connecting rod is disposed between the deflection structure and the abutment rod. The top of the connecting rod is rotatably connected to the deflection structure, and the bottom is rotatably connected to the top of the abutment rod.

[0016] In the protective device of the lightning protection mechanism of electrical equipment as described above, the deflection structure may optionally include: a first rotating plate, which is rotatably installed inside the cavity;

[0017] The second rotating plate is fixedly installed at the end of the first rotating plate facing the air inlet, and the top of the connecting rod is rotatably connected to the second rotating plate.

[0018] In the protective device of the lightning protection mechanism of electrical equipment as described above, the supporting structure may optionally include: a wind baffle is fixedly installed inside the wind plate, and the wind baffle is located between the air inlet and the second rotating plate.

[0019] In the protective device of the lightning protection mechanism of electrical equipment of this utility model, the wind plate is sleeved on the outer surface of the lightning rod to protect the lightning rod. At the same time, the support structure can support the lightning rod from the leeward end. When the wind force is stronger, the wind plate rotates with the wind direction. The strong wind enters the wind plate through the air inlet and drives the deflection structure to rotate, so that the abutment rod inside the support tube presses against the annular fixing plate, thereby enhancing the support force of the support structure on the lightning rod, achieving the effect that the stronger the wind, the stronger the support force on the lightning rod.

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] As shown in Figures 1 to 5, a typical embodiment of this utility model provides a protective device for a lightning protection mechanism of electrical equipment, including: a support frame 1, which serves as the base of the lightning rod and is fixedly installed on a building or metal frame by bolts;

[0029] Main pipe 2, installed on support frame 1, is used to install lightning rods;

[0030] An annular fixing plate 3 is fixedly installed between the support frame 1 and the main pipe 2;

[0031] Wind plate 4 is fitted onto the outer surface of the lightning rod;

[0032] The support structure 5 is installed at the bottom of the air plate 4. The bottom of the support structure 5 is slidably engaged with the annular fixing plate 3, and the support structure 5 is in an inclined state.

[0033] In this embodiment, the wind plate 4 is fitted onto the outer surface of the lightning rod to protect it. When encountering strong winds, the wind plate 4 can rotate with the wind direction to be consistent with the wind direction, causing the support structure 5 to rotate. The bottom of the support structure 5 slides along the circumferential direction of the annular fixing plate 3 to the leeward end. The support structure 5 is in an inclined state, which provides diagonal support for the wind plate 4. The wind plate 4 is fitted onto the lightning rod, and the support structure 5 provides diagonal support for the lightning rod, thus supporting the lightning rod from the leeward end.

[0034] The support structure 5 includes: a support tube 5-1, the top of which is fixedly connected to the bottom of the air plate 4, and the bottom of which abuts against the annular fixing plate 3. The annular fixing plate 3 has an annular groove 3-1, and the bottom of the support tube 5-1 slides in conjunction with the annular groove 3-1.

[0035] In this embodiment, the bottom of the support tube 5-1 is set inside the annular groove 3-1. When the wind plate 4 rotates, the support tube 5-1 slides stably in the annular groove 3-1 along the circumferential direction of the annular fixed plate 3. When encountering strong wind, the support tube 5-1 is set inside the annular groove 3-1 and contacts the inner wall of the annular groove 3-1, so that the oblique support effect of the support tube 5-1 is better.

[0036] The support structure 5 also includes: a stop rod 5-2, which is slidably sleeved inside the support tube 5-1, and the bottom of the stop rod 5-2 can abut against the annular fixing plate 3;

[0037] An air inlet 4-1 is provided on the leeward end of the ventilation plate 4, which is connected to the interior of the ventilation plate 4. The support pipe 5-1 is connected to the air inlet 4-1.

[0038] A protective device for a lightning protection mechanism of electrical equipment further includes:

[0039] The deflection structure 6 is rotatably installed inside the air plate 4;

[0040] The connecting rod 7 is located between the deflection structure 6 and the abutment rod 5-2. The top of the connecting rod 7 is rotatably connected to the deflection structure 6, and the bottom is rotatably connected to the top of the abutment rod 5-2.

[0041] In this embodiment, when encountering strong winds, the wind deflector 4 rotates to align with the wind direction. The air inlet 4-1 on the wind deflector 4 then faces the strong wind, and the strong wind airflow enters the interior of the wind deflector 4 through the air inlet 4-1. This causes the deflection structure 6 to rotate upward under the influence of the strong wind airflow, which in turn causes the connecting rod 7 to push down the abutment rod 5-2. The bottom of the abutment rod 5-2 then comes into contact with the annular groove 3-1 on the annular fixing plate 3. The stronger the wind, the greater the pressure of the abutment rod 5-2, and the greater the supporting force of the annular fixing plate 3 on the abutment rod 5-2. This achieves the effect that the stronger the wind, the stronger the support force for the lightning rod.

[0042] The deflection structure 6 includes: a first rotating plate 6-1, which is rotatably installed inside the cavity;

[0043] The second rotating plate 6-2 is fixedly installed at the end of the first rotating plate 6-1 facing the air inlet 4-1, and the top of the connecting rod 7 is rotatably connected to the second rotating plate 6-2.

[0044] In this embodiment, when the wind is strong, the airflow enters the wind plate 4 through the air inlet 4-1 and pushes the first rotating plate 6-1 to rotate upward. The upward rotation of the first rotating plate 6-1 can drive the second rotating plate 6-2 to rotate downward. The downward rotation of the second rotating plate 6-2 can drive the abutment rod 5-2 to press down. When the wind is weak, the airflow becomes smaller. Under the action of its own weight, the second rotating plate 6-2 rotates downward, causing the second rotating plate 6-2 to deflect upward, so that the abutment rod 5-2 is displaced upward and reset.

[0045] A baffle plate 8 is fixedly installed inside the air inlet 4, and the baffle plate 8 is located between the air inlet 4-1 and the second rotating plate 6-2.

[0046] In this embodiment, an opening is provided below the wind deflector 8. The wind deflector 8 is located between the air inlet 4-1 and the second rotating plate 6-2. The airflow enters the interior of the wind deflector 4 through the air inlet 4-1. The wind deflector 8 concentrates and guides the airflow to the opening, so that the airflow can concentrate and contact the first rotating plate 6-1. During the process of the first rotating plate 6-1 being pushed upward by the airflow, the power loss of the airflow is minimized.

[0047] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
