Description

Technical Field

[0001] The utility model relates to the technical field of electric lightning protection, in particular to an electric lightning protection grounding device. Background Art

[0002] Lightning rods, also known as lightning protection rods, are devices used to protect buildings, tall trees, etc. from lightning strikes. A lightning arrester is installed on the top of the protected object and connected to the underground discharge ground grid with a wire that meets the specifications. The specifications of lightning rods must comply with GB standards. The height specifications of lightning rods required for each lightning protection category are different. When the thundercloud discharges close to the ground, it distorts the ground electric field. At the top of the lightning rod, a space with a concentrated local electric field is formed to affect the development direction of the lightning leader discharge, guide the lightning to discharge to the lightning rod, and then introduce the lightning current into the earth through the grounding down conductor and the grounding device, so that the protected object is protected from lightning strikes.

[0003] According to application number 202221671078.2, an electric lightning protection grounding device is disclosed, including an insulating base plate and a top insulating plate, a threaded column is fixedly installed on the bottom of the insulating base plate, an inner rod is threadedly connected to the outer side of the threaded column, an outer rod is movably sleeved on the outer side of the bottom end of the inner rod, a mounting plate is fixedly installed on the bottom of the outer rod, a fastening bolt is inserted into the inside of the threaded column, adjustment holes are provided inside the inner rod and the outer rod, a cone ring is fixedly installed on the top of the outer rod, and an insulating part is fixedly installed on the top of the insulating base plate.

When the device is completely disassembled later, due to the rust of the nuts, not only the installation efficiency is slow, but there is a high probability that it cannot be disassembled, which will affect the subsequent normal use. Therefore, it is necessary to develop an electric lightning protection grounding device. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a mounting base 1, an adjusting component 2 is mounted on the upper surface of the mounting base 1, and a group of reinforcement plates are mounted on the upper surface of the mounting base 1. The adjustment component 2 can be made more stable by setting the reinforcement plates. At the same time, the mounting base 1 is made of aluminum-copper rare earth alloy, which has the advantages of good strength, high hardness, good conductivity and strong corrosion resistance, thereby extending the service life of the safety base 1.

[0025] The adjustment assembly 2 comprises a telescopic cylinder 201 , the bottom surface of the telescopic cylinder 201 is fixedly connected to the upper surface of the mounting base 1 , and the upper surface of the telescopic cylinder 201 is slidably connected to a telescopic rod 202 .

[0026] Through the sliding connection between the telescopic tube 201 and the telescopic rod 202, the extension of the telescopic rod 202 can be adjusted, thereby achieving adjustment of the height of the device, and ensuring the subsequent normal use of the grounding device.

[0027] A group of threaded holes 203 arranged at equal distances are provided on the outer surface of the telescopic rod 202, a hexagonal bolt 204 is threadedly connected to the outer surface of the telescopic tube 201, and one end of the hexagonal bolt 204 passes through the telescopic tube 201 and is threadedly connected to the inner wall of the threaded hole 203, and the upper surface of the telescopic rod 202 is fixedly connected to the bottom surface of the fixing plate 3.

[0028] The hexagonal bolt 204 is used to thread the telescopic tube 201, and then through the provided threaded hole 203, when one end of the hexagonal bolt 204 is rotated into the inside of the threaded hole 203, the telescopic rod 202 can be limited and fixed, thereby ensuring the stability of the telescopic rod 202 when in use.

[0029] A fixing plate 3 is disposed above the adjusting component 2 . An insulating component 4 is installed on the upper surface of the fixing plate 3 . The insulating component 4 includes four connecting rings 401 . The four connecting rings 401 are all fixedly connected to the outer surface of the fixing plate 3 .

[0030] The connection ring 401 can provide a certain convenience for moving the fixing plate 3 up and down, making it more convenient for subsequent staff to operate the device.

[0031] An insulating plate 403 is disposed above the fixing plate 3 , and a group of insulating rods 402 and a connecting column 404 are installed between the insulating plate 403 and the fixing plate 3 .

[0032] Since the insulating rod 402 and the insulating plate 403 are both made of aluminum-copper rare earth alloy, the service life of the device can be increased.

[0033] The upper surface of the insulating plate 403 is fixedly connected to the bottom surface of the needle body 5. The needle body 5 is arranged above the insulating component 4. The needle body 5 is fixed to the upper surface of the insulating plate 403 by a group of fastening bolts. The bolt-type fixation makes it convenient for subsequent staff to disassemble or repair the needle body 5, and can ensure the normal use of the subsequent needle body 5.

[0034] At the same time, the materials of the connecting ring 401 and the connecting column 404 are both aluminum-copper rare earth alloy. The aluminum-copper rare earth alloy has the advantages of good strength, high hardness, good conductivity and strong corrosion resistance, which makes the service life of the safety base 1 longer.

[0035] A snap-on assembly 6 is installed on the bottom surface of the mounting base 1. The snap-on assembly 6 includes four connecting tubes 601 of the same size. The four connecting tubes 601 are fixedly connected to the outer surface of the mounting base 1. Two through grooves 602 are provided on the outer surface of each connecting tube 601, and the inner wall of the through groove 602 is hinged with a snap-on plate 603 through two hinge rods.

[0036] The through slot 602 is adapted to the size of the snap-in plate 603, which can ensure the normal subsequent unfolding of the snap-in plate 603 and the normal subsequent snap-in fixation of the snap-in plate 603. At the same time, the snap-in plate 603 is pushed by the provided hinged rod, and the snap-in plate 603 will rotate around the center of the hinged rod, thereby facilitating subsequent snap-in.

[0037] The side surfaces of each set of clamping plates 603 that are close to each other are fixedly connected with a connecting rod 604, and the end of the connecting rod 604 that is away from the clamping plate 603 is fixedly connected with a conical block 605, the upper surfaces of the four connecting tubes 601 are slidably connected with sliding rods 606, and the outer surfaces of the sliding rods 606 are sleeved with springs 607, and the top of each sliding rod 606 is fixedly connected with a push handle 608.

[0038] Through the sliding connection between the slide rod 606 and the connecting tube 601, and by utilizing the spring 607 sleeved on the surface of the slide rod 606, the slide rod 606 has a certain reset ability. One end of the spring 607 away from the upper surface of the connecting tube 601 contacts the bottom surface of the push handle 608, and the other end contacts the upper surface of the connecting tube 601. The connection relationship of the spring 607 is explained in detail to facilitate subsequent staff to assemble the device.

[0039] The bottom end of each sliding rod 606 is fixedly connected to a conical plate 609 , and a guide groove 610 is formed on the outer surface of the conical plate 609 .

[0040] When the slide bar 606 moves downward, it will drive the conical plate 609 to move. When the conical block 605 slides into the guide groove 610, as the slide bar 606 moves downward, the two conical blocks 605 will move away from each other, and then the two clamping plates 603 can be moved away from each other, thereby achieving the unfolding of the clamping plates 603 and the clamping effect.

[0041] Two clamping holes 611 are provided on the upper surface of each push handle 608, and a fixing ring 612 is fixedly connected to the outer surface of each connecting tube 601, and two winding rings 613 are fixedly connected to the outer surface of the fixing ring 612, and a connecting rope 614 is wound around the outer surface of each winding ring 613, and a hook 615 is fixedly connected to the end of the connecting rope 614 away from the winding ring 613.

[0042] When the slide bar 606 moves downward to a suitable position, the connecting rope 614 is appropriately wound around the surface of the winding ring 613 according to the position of the push handle 608, and then the hook 615 is hung inside the clamping hole 611, thereby achieving the limited fixation of the push handle 608, thereby ensuring the clamping effect of the device and the subsequent normal use of the device.

[0043] Working principle: when installing this device, first start drilling a hole in the ground at the specified position using an electric drill, then insert the expansion tube, then align the four connecting tubes 601 with the position of the hole and insert them, then push the slide bar 606 downward through the push handle 608. During the pushing process, the spring 607 will be compressed, and the conical plate 609 will move downward. When the conical block 605 slides to the inside of the guide groove 610, as the staff continues to move the slide bar 606 downward, and then using the inclination angle of the guide groove 610, the clamping plate 603 can be slowly extended outward, so that it contacts the expansion tube, thereby fixing the device, and then according to the position of the push handle 608, an appropriate connecting rope 614 is wrapped around the surface of the winding ring 613, and finally the hook 615 is inserted into the inside of the clamping hole 611 to complete the limit fixation of the push handle 608.

[0044] When disassembling the grounding device, first take out the hook 615 from the inside of the card hole 611, and hold the push handle 608 during the removal process. When the two hooks 615 are taken out from the inside of the card hole 611, the compressed force of the spring 607 will be released, which will drive the conical plate 609 to move upward. When the conical block 605 is disengaged from the inside of the guide groove 610, the two clamping plates 603 will move in a similar direction, thereby resetting the clamping plates 603. Then, the grounding device can be disassembled by pulling the device up and down without affecting the normal use of subsequent roads.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
