[0001] The present application relates to the field of building lightning protection equipment, and in particular to a meteorological lightning protection grounding device. Background Art

[0002] Lightning is a common natural phenomenon that can be extremely destructive to meteorological equipment, buildings, and more. In the meteorological field, meteorological equipment often requires lightning protection and grounding devices to ensure safe operation and accurate data collection.

[0003] Agricultural meteorological instruments installed outdoors in fields can also be affected by lightning. In particular, the shells of many meteorological instruments are made of metal, which has good conductivity. Although the meteorological instruments are installed in the soil, once struck by lightning, the components inside the shell will be affected and damaged. Utility Model Content

[0004] The present application provides a meteorological lightning protection grounding device, which is used to solve the problem that components of agricultural meteorological instruments may be damaged by lightning.

[0005] The present application provides a meteorological lightning protection grounding device, which is installed on a meteorological instrument. The meteorological instrument includes an embedded seat, a supporting column and a shell. The supporting column is plugged into the embedded seat. The meteorological lightning protection grounding device includes a lightning rod, a down conductor and a grounding body. The lightning rod is arranged above the shell, and the lightning rod is insulated and connected to the shell. The down conductor is arranged in the supporting column, and a through cavity is provided in the supporting column. The through cavity passes through the embedded seat along the axis of the column, and the down conductor passes through the supporting column along the axis of the supporting column. The down conductor is spaced apart from the supporting column, and the upper end of the down conductor is electrically connected to the lightning rod. The grounding body is arranged on the lower side of the embedded seat, and the grounding body is spaced apart from the embedded seat, and the lower end of the down conductor is electrically connected to the grounding body.

[0006] A lightning rod is installed on the top of the meteorological instrument in this application. The height of the lightning rod is higher than other components, which can better guide lightning. The down conductor and the supporting column are spaced apart to avoid leakage of lightning when the down conductor conducts lightning. The grounding body is buried on the lower side of the embedded seat to avoid conductivity between the grounding body and the embedded seat. The lightning rod, down conductor and grounding body in this solution are spaced or insulated from the meteorological instrument at all times, which can avoid the meteorological instrument from being energized during the lightning guidance process, thereby providing lightning protection for the meteorological instrument and preventing lightning from affecting the normal operation of the components inside the meteorological instrument.

[0007] In some embodiments of the present application, a groove is formed on the upper side of the grounding body, and the lower end of the down conductor is bent to form a bent portion, which extends into the groove. The meteorological lightning protection grounding device also includes a fixing block that fills the opening of the groove and abuts the bent portion. The fixing block increases the contact surface between the bent portion and the groove, and the fixing block ensures more stable contact between the bent portion and the groove, thereby increasing the strength and stability of the connection between the down conductor and the grounding body.

[0008] In some embodiments of the present application, a recessed groove is formed between the fixed block and the side wall of the groove, and an internal thread is formed on the annular wall of the recessed groove; the meteorological lightning protection grounding device also includes a threaded connector, on which an external thread matching the internal thread is formed, and the threaded connector is threadedly connected to the recessed groove between the fixed block and the groove.

[0009] The threaded connector and the recessed groove between the fixed block and the grounding body can be threadedly connected, thereby improving the connection strength between the fixed block and the grounding body and making the fixed block and the bent portion abut stably. At this time, the contact between the bent portion and the inner wall of the groove can be stabilized, thereby stabilizing the conductive effect.

[0010] In some embodiments of the present application, a plurality of recesses are provided, spaced apart around the opening of the groove; a plurality of threaded connectors are provided, each corresponding to one of the recesses, and each threaded connector is threadedly connected to the corresponding recess. The plurality of recesses and threaded connectors can improve the connection strength between the fixing block and the bent portion.

[0011] In some embodiments of the present application, the support column extends through the top wall of the housing along its axis and extends beyond the top wall of the housing. A down conductor extends through the top of the support column, and a lightning receptor is disposed on the down conductor. The down conductor extending through the top of the support column and connecting to the lightning receptor facilitates installation of the lightning receptor and the down conductor.

[0012] In some embodiments of the present application, the meteorological lightning protection grounding device further includes two insulating sealing rings, one at each end of the support column, and the down conductor passes through both insulating sealing rings. Both insulating sealing rings are hermetically connected to the down conductor. The insulating sealing rings prevent water and insects from entering between the support column and the down conductor, thereby improving the independence of the support column and the down conductor.

[0013] In some embodiments of the present application, the meteorological lightning protection grounding device further includes an insulating filler, which is filled between the down conductor and the support column. The insulating filler can further block the space between the down conductor and the support column to prevent lightning from affecting the meteorological instrument.

[0014] In some embodiments of the present application, the meteorological lightning protection grounding device further includes a grounding grid disposed below the grounding body and electrically connected to the grounding body. The grounding grid can improve the electrical conductivity of the grounding body and increase the rate at which lightning is guided underground.

[0015] In some embodiments of the present application, the meteorological lightning protection grounding device further includes a plurality of extension pins disposed at the bottom of the grounding grid and spaced apart. The extension pins can improve the stability of the grounding grid and further increase the conduction rate of lightning conducted from the grounding body to the soil.

[0024] Lightning is a common natural phenomenon that can be extremely destructive to meteorological equipment, buildings, and more. In the meteorological field, meteorological equipment often requires lightning protection and grounding devices to ensure safe operation and accurate data collection.

[0025] Agricultural meteorological instruments installed outdoors in fields can also be affected by lightning. In particular, the shells of many meteorological instruments are made of metal, which has good conductivity. Although the meteorological instruments are installed in the soil, once struck by lightning, the components inside the shell will be affected and damaged.

[0026] To do this, please refer to Figure 1 The present application provides a meteorological lightning protection grounding device, which is installed on a meteorological instrument 1. The meteorological lightning protection grounding device and the meteorological instrument 1 can be reconstructed as a unit and connected in a recombined manner, so that the meteorological lightning protection grounding device and the meteorological instrument 1 are stably connected and can achieve corresponding lightning protection effects.

[0027] Please refer to Figure 1 The meteorological instrument 1 includes an embedded seat 11, a support column 12, and a housing 13. The support column 12 is plugged into the embedded seat 11. Various meteorological monitoring components can be installed in the housing 13 of the meteorological instrument 1. Wind speed detection equipment, bird repellent devices, etc. can also be installed on the housing 13. The housing 13 can be metal or non-metal, and the housing 13 and the support column 12 can be fixedly connected.

[0028] Please refer to Figure 1 The meteorological lightning protection grounding device includes a lightning rod 2, a down conductor 3, and a grounding body 4. The lightning rod 2, down conductor 3, and grounding body 4 are commonly used structures in lightning protection. This structure can be combined to complete the operation sequence of attracting, transmitting, and introducing lightning into the ground, and realize lightning protection for the meteorological instrument 1.

[0029] Please refer to Figure 1 The lightning receptor 2 is disposed above the housing 13 and is insulated from the housing 13. The lightning receptor 2 refers to the lightning rod, lightning strip (line), lightning net, and metal roof and metal components used for lightning termination. It can be a lightning rod, a lightning strip, or a lightning net, with a lightning rod being preferred. The starting height of the lightning receptor 2 can be higher than the height of any component on the housing 13.

[0030] Please refer to Figure 1 The down conductor 3 is disposed within the support column 12. The support column 12 has a through cavity therein. The through cavity extends through the embedded seat 11 along the axis of the column. The down conductor 3 extends through the support column 12 along the axis of the column. The down conductor 3 is spaced apart from the support column 12, and the upper end of the down conductor 3 is electrically connected to the lightning receptor 2. The down conductor 3 is a metallic conductor that connects the lightning receptor 2 (such as a lightning rod) to the grounding device. Its primary function is to safely conduct lightning current received by the lightning receptor 2 to the grounding device.

[0031] Please refer to Figure 1 Down conductor 3 is typically made of metal materials such as round steel or flat steel to ensure stable conduction of lightning current during long-term use. Down conductor 3 should be kept straight during installation to avoid bending and breaking. The gap between down conductor 3 and support column 12 can be set between 1 / 3 and 1 / 5 of the diameter of support column 12, and the spacing can be equal throughout or locally.

[0032] Please refer to Figure 1 The grounding body 4 is located below the embedded socket, spaced apart from the embedded socket. The lower end of the down conductor 3 is electrically connected to the grounding body 4. A grounding system is the collective name for the buried grounding body 4 and the grounding wire connecting it to the grounded portion of the electrical equipment. Its primary function is to safely discharge lightning current conducted by the down conductor 3 into the earth, thereby protecting the building, its internal equipment, and personnel.

[0033] Please refer to Figure 1 The grounding body 4 can be a natural grounding body 4, an artificial grounding body 4, or a building grounding body 4. In this solution, the artificial grounding body 4 is preferred. The gap between the grounding body 4 and the embedded seat can be 1 to 3 times the thickness of the embedded seat. The grounding body 4 can be made of copper or iron.

[0034] Please refer to Figure 1In the present application, a lightning rod 2 is installed on the top of the meteorological instrument 1. The lightning rod 2 is higher than other components, which can better guide lightning. The down conductor 3 and the supporting column 12 are spaced apart, which can avoid leakage of lightning when the down conductor 3 conducts lightning. The grounding body 4 is buried under the embedded seat 11, which can avoid electrical conduction between the grounding body 4 and the embedded seat 11.

[0035] Please refer to Figure 1 In this solution, the lightning receptor 2, down conductor 3 and grounding body 4 are separated or insulated from the meteorological instrument 1 at all places, which can prevent the meteorological instrument 1 from being charged during the lightning guidance process, thereby providing lightning protection for the meteorological instrument 1 and preventing lightning from affecting the normal operation of the components in the meteorological instrument 1.

[0036] Please refer to Figure 1 It should be noted that when the down conductor 3 is conducting lightning, since the shell 13 and the supporting column 12 are arranged around the down conductor 3, magnetic and electric fields may appear on the shell 13 and the supporting column 12. At this time, since the lightning transmission time on the down conductor 3 is short and the supporting base is buried in the soil, these additional products will have a slight impact on the components in the shell 13, or no impact.

[0037] Please refer to Figure 1 In some examples, a groove 41 is formed on the upper side of the grounding body 4, and the lower end of the down conductor 3 is bent to form a bent portion 31, which extends into the groove 41. The meteorological lightning protection grounding device also includes a fixing block 42, which fills the opening of the groove 41 and abuts the bent portion 31. The fixing block 42 increases the contact surface between the bent portion 31 and the groove 41, and the fixing block 42 can ensure more stable contact between the bent portion 31 and the groove 41, thereby increasing the connection strength and stability between the down conductor 3 and the grounding body 4.

[0038] In some examples, the shapes of the groove 41 and the bending portion 31 can be set to correspond, for example, the surface of the bending portion 31 can be arc-shaped, in which case the groove 41 can be an arc-shaped groove; or the bending portion 31 can be square, in which case the groove 41 can be a square groove.

[0039] The bending portion 31 can be formed by directly bending the bottom end of the down conductor 3, or it can be integrally formed or welded. The angle between the axis of the bending portion 31 and the axis of the down conductor 3 can be 90°, or 85°, 80°, 95°, 105° or 110°.

[0040] In some examples, the fixing block 42 can be made of a metal conductive material, such as iron, copper, or stainless steel, or can also be made of a plastic material, both of which can achieve a limiting effect on the bending portion 31 .

[0041] Please refer to Figure 1In some examples, a recessed groove is formed between the fixing block 42 and the side wall of the groove 41, and an internal thread is formed on the annular wall of the recessed groove; the meteorological lightning protection grounding device also includes a threaded connector 43, on which an external thread that matches the internal thread is formed, and the threaded connector 43 is threadedly connected to the recessed groove between the fixing block 42 and the groove 41.

[0042] The threaded connector 43 and the recessed groove between the fixed block 42 and the grounding body 4 can be threadedly connected, thereby improving the connection strength between the fixed block 42 and the grounding body 4, and making the fixed block 42 abut against the bent portion 31 stably. At this time, the contact between the bent portion 31 and the inner wall of the groove 41 can be stabilized, thereby stabilizing the conductive effect.

[0043] In some examples, the threaded member may be a cross head bolt, or may be a conventional hex head bolt, or may be a threaded post.

[0044] Please refer to Figure 1 In some examples, multiple recesses are provided, spaced apart around the opening of the groove 41. Multiple threaded connectors 43 are provided, corresponding one to each of the recesses, and threadedly connected to the corresponding recesses. Multiple recesses and threaded connectors 43 can enhance the connection strength between the fixing block 42 and the bent portion 31.

[0045] In some examples, the number of the sinks may be 2 to 6, preferably 2, and the two sinks may be disposed on opposite sides of the A-zi fixing block 42 .

[0046] Please refer to Figure 1 In some examples, along the axis of the support column 12, the support column 12 passes through the top wall of the housing 13 and extends outside the top wall of the housing 13. The down conductor 3 passes through the top of the support column 12, and the lightning receptor 2 is disposed on the down conductor 3. The down conductor 3 passes through the top of the support column 12 and is connected to the lightning receptor 2, which facilitates the installation of the lightning receptor 2 and the down conductor 3.

[0047] In some examples, the lightning receptor 2 may be directly connected to the down conductor 3 via a threaded structure, or may be connected via other conductive elements.

[0048] Please refer to Figure 1 In some examples, the meteorological lightning protection grounding device further includes two insulating sealing rings 5 ​​, one at each end of the support column 12 . The down conductor 3 passes through the two insulating sealing rings 5 ​​, and both insulating sealing rings 5 ​​are sealed to the down conductor 3 . The insulating sealing rings 5 ​​prevent water and insects from entering between the support column 12 and the down conductor 3 , thereby improving the independence between the support column 12 and the down conductor 3 .

[0049] In some examples, the insulating sealing ring 5 may be a rubber ring or a plastic ring.

[0050] Please refer to Figure 1 In some examples, the meteorological lightning protection grounding device further includes an insulating filler 6, which is filled between the down conductor 3 and the support column 12. The insulating filler 6 can further block the space between the down conductor 3 and the support column 12 to prevent lightning from affecting the meteorological instrument 1.

[0051] In some examples, the insulating filler 6 may be rubber, plastic, or foam.

[0052] Please refer to Figure 1 In some examples, the meteorological lightning protection grounding device further includes a grounding grid 7, which is disposed below the grounding body 4 and electrically connected to the grounding body 4. The grounding grid 7 can improve the electrical conductivity of the grounding body 4 and increase the rate at which lightning is guided underground.

[0053] In some examples, the grounding grid 7 may be a conventional metal mesh, or may be woven with metal ribs to form a spatial structure, so as to further increase the contact area with the soil and improve the conduction efficiency of lightning.

[0054] Please refer to Figure 1 In some examples, the meteorological lightning protection grounding device further includes a plurality of extension pins 71 disposed at the bottom of the grounding grid 7 and spaced apart. The extension pins 71 can improve the stability of the grounding grid 7 and further increase the conduction rate of lightning conducted from the grounding body 4 to the soil.

[0055] In some examples, the resistivity of the extension pin 71 can be less than or equal to the resistivity of the ground body 4. In this case, the extension pin 71 can be made of any metal material including stainless steel, iron, copper, and silver. The extension pin 71 can be in the shape of a column, which can be a straight column or a curved column.
