Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical engineering, in particular to a lightning protection grounding device for electromechanical engineering equipment. Background Art

[0002] Mechanical and electrical engineering includes electrical engineering technology, automatic control and instrumentation, water supply and drainage, mechanical equipment installation, container installation, heating, ventilation and air-conditioning engineering, building intelligent engineering, fire protection engineering, equipment and pipeline corrosion protection and insulation technology, etc., while mechanical and electrical equipment generally refers to machinery, electrical appliances and electrical automation equipment. Some mechanical and electrical equipment installed at high altitudes or on the rooftops are likely to be struck by lightning during thunderstorms, so lightning protection and grounding devices are usually installed. The lightning protection and grounding devices are mainly composed of surge protectors, connecting conductors, and grounding structures. Surge protectors can also be called lightning arresters, lightning rods, etc. They are installed at high places in the open air to guide lightning, and then discharge the current to the earth through connecting conductors and grounding structures to avoid lightning damaging the mechanical and electrical equipment.

[0003] During the use of existing lightning protection grounding devices, several components are very easy to corrode, namely the grounding wire and its connecting screws, the welding part of the device, the equalizing belt, the grounding body, etc. The two ends of the grounding wire are connected to the lightning arrester and the grounding body through terminal blocks and screws. The screws are easily rusted due to long-term exposure, which increases the difficulty of subsequent maintenance and may cause corrosion together with the terminals and other structures in contact with them, thereby increasing the resistance and reducing the grounding effect.

[0006] By adopting the above technical scheme, the connecting part between the grounding wire and the lightning arrester is sealed by the cooperation of the insulating protective cover, the cover and the sealing arc plate, which effectively alleviates the occurrence of rust, thereby extending the service life of the lightning protection grounding device. The split design of the cover is convenient for installation, avoiding interference of the grounding wire on the installation of the cover, and the setting of the positioning rod and the positioning hole facilitates the combination and alignment of the two covers, avoiding the phenomenon that the threads on the cover are not aligned and cannot be assembled. The moisture in the insulating protective cover can enter the placement groove through the breathable net and be adsorbed by the bagged desiccant, thereby reducing the relative humidity in the insulating protective cover, further alleviating the rust of the connecting part between the grounding wire and the lightning arrester. When the bagged desiccant is fully adsorbed, the support cover can be removed and the bagged desiccant can be replaced.

Then the staff rotates the cover and installs it on the bottom of the insulating protective cover, and the assembly work is completed.

[0009] Furthermore, the positioning rods and positioning holes are both provided in plurality, and the positioning rods are matched with the positioning holes.

[0010] By adopting the above technical solution, the staff closes the two covers. At this time, the two covers are positioned by the positioning rod and the positioning hole to avoid misalignment of the threads on the covers due to structural deviation.

[0011] Furthermore, the sealing arc plate is semicircular, and both sealing arc plates are made of rubber material.

[0012] By adopting the above technical solution, the two covers are closed and the grounding wire is located between the two sealing arc plates. The connection part between the grounding wire and the lightning arrester is sealed by the cooperation of the insulating protective cover, the cover and the sealing arc plate, thereby effectively alleviating the occurrence of rust.

[0013] Furthermore, the support cover is detachably connected to the placement groove through friction force.

[0014] By adopting the above technical solution, the staff puts the bagged desiccant into the placement slot, and then the staff inserts the support cover into the placement slot to prevent the bagged desiccant from falling.

[0015] Furthermore, a mounting bolt passes through one side of the mounting frame, a lightning arrester is installed on the other side of the mounting frame, a grounding bolt is connected to the bottom of the lightning arrester, and a grounding nut and a fastening nut are respectively sleeved on the outside of the grounding bolt.

[0016] By adopting the above technical solution, when lightning occurs, the lightning arrester attracts lightning to prevent it from damaging the electromechanical equipment. Then the lightning arrester transmits the current to the grounding wire through the grounding bolt and the grounding nut, and then the grounding wire discharges the current to the earth through the grounding structure.

[0017] Furthermore, a first sealing plug and a second sealing plug are respectively connected to both sides of the outer surface of the mounting bolt, and both the first sealing plug and the second sealing plug are made of rubber material.

[0018] By adopting the above technical solution, the staff will sleeve the first sealing plug and the second sealing plug on the outside of the mounting bolt to shield and seal it, so as to delay the corrosion of the mounting bolt.

[0019] Furthermore, the first sealing plug and the second sealing plug are both detachably connected to the mounting bolts.

[0033] The two covers 10 are detachably connected through the positioning rod 16 and the positioning hole 17. There are multiple positioning rods 16 and positioning holes 17. The positioning rods 16 and the positioning holes 17 are adapted to each other.
