Description

TECHNICAL FIELD

[0001] The present application relates to the field of civil engineering and lightning protection grounding technology, and particularly relates to a long-acting comprehensive ground grid system applied to an interval base station. BACKGROUND

[0002] Lightning protection of a base station is very important. First, the risk of lightning strike of the base station is relatively high. On one hand, the base station is provided with a high-rise iron tower. On the other hand, in order to achieve signal coverage, the base station is generally selected to be on a mountain top, a roof or an open highland, and the probability of being hit by a direct lightning is 3-5 times that of an ordinary building. Second, the direct loss of the base station after lightning strike is large. The communication equipment in the base station is delicate and afraid of electricity and magnetism. The radio frequency, baseband and power supply module in the base station are all low-voltage microelectronic devices, and the chip withstand voltage is usually lower than 50 V. Even if the lightning does not directly hit, as long as a few thousand volts of surge is induced on the feeder, power line or sky surface, it is enough to break down the plate and melt the copper foil. In addition, after the base station is struck by lightning, the secondary disaster chain reaction loss is immeasurable, for example, communication interruption, data loss and the like, which seriously affects the normal life and production of nearby residents and factories.

[0003] Compared with ordinary buildings, the protection requirement of the base station is more complex. The machine room, iron tower and power box transformer equipment in the base station all need to be protected. In the prior art, independent lightning protection is generally performed on each key part, that is, a group of grounding electrodes are respectively arranged for the machine room, iron tower and power box transformer, and then the flat steel is randomly connected in parallel.

[0004] This kind of dispersed grounding mode has the following obvious defects: first, the construction is complex, and a trench needs to be separately excavated for each facility and a grounding body needs to be laid, resulting in large engineering quantity, high cost and large occupied area. Especially when the power box transformer is increased or changed during the upgrading and reconstruction of the base station, repeated grounding construction is required, which increases the difficulty of upgrading and reconstruction of the base station. Second, when lightning strikes, due to the difference in grounding resistance of each independent grounding device, a dangerous potential difference between the devices is caused, which easily causes ground potential counterattack and damages the delicate communication equipment. Finally, the independent grounding system is not convenient for unified maintenance management and state monitoring.

[0005] Therefore, there is an urgent need in the art for an interval base station grounding solution capable of realizing collaborative protection, balancing potential, simplifying construction and reducing cost. SUMMARY

[0040] The grounding net facility for interval base station provided by the embodiments of the present application will be described in detail below in combination with the drawings and specific embodiments.

[0042] Figure 2A top view of the ground net facility for the section base station provided by the embodiment of the present application.

[0043] As shown in Figure 1 and Figure 2 The core of the ground net facility for the section base station provided by the embodiment of the present application is to set a unified ground net component 400.

[0044] The ground net component 400 is buried underground; the ground net component 400 includes a horizontal loop grounding body 410 and a plurality of vertical grounding bodies 420, the horizontal loop grounding body 410 is located around the base station, and encloses a mounting area in the base station, the base station room 1, the power box transformer equipment 3 and the iron tower 2 are located in the mounting area;

[0045] The base station room lightning protection component 100 is installed on the base station room 1, and is used for providing lightning protection for the base station room 1; the base station room lightning protection component 100 is electrically connected with the horizontal loop grounding body 410;

[0046] The iron tower lightning protection component 200 is installed on the iron tower 2, and is used for providing lightning protection for the iron tower 2; the iron tower lightning protection component 200 is electrically connected with the horizontal loop grounding body 410;

[0047] And at least one power box transformer equipment lightning protection component 300 is installed on the power box transformer equipment 3, and is used for providing lightning protection for the power box transformer equipment 3; the power box transformer equipment lightning protection component 300 is electrically connected with the horizontal loop grounding body 410.

[0048] The component includes a horizontal loop grounding body 410 buried underground and a plurality of vertical grounding bodies 420. The horizontal loop grounding body 410 surrounds the base station area, and encloses the base station room 1, the iron tower 2 and the power box transformer equipment 3 in the mounting area inside it. The vertical grounding bodies 420 are vertically punched into the ground at equal intervals, and are reliably welded with the horizontal loop grounding body 410, and together constitute a low-resistance grounding foundation.

[0049] The base station room 1 is electrically connected with the horizontal loop grounding body 410 through the base station room lightning protection component 100, the iron tower 2 is electrically connected with the horizontal loop grounding body 410 through the iron tower lightning protection component 200, and the power box transformer equipment 3 is electrically connected with the horizontal loop grounding body 410 through the power box transformer equipment lightning protection component 300, to access this unified ground net component 400.

[0050] The horizontal loop grounding body 410 of the grounding net assembly 400 constitutes a unified grounding body surrounding the periphery of the base station, which can connect the base station machine room lightning protection assembly 100, the lightning protection assembly 200 of the iron tower, and the lightning protection assembly 300 of the power box transformer device into an integrated whole, effectively balances the potential between the devices, greatly reduces the risk of high potential counterattack when lightning strikes, and improves the safety of the overall system.

[0051] It is not necessary to dig a trench and lay a grounding body for each facility, which can reduce the construction difficulty and construction cost; when the base station is upgraded, the power box transformer can be arbitrarily added in the base station area, and only a simple electrical connection is needed to realize the lightning protection of the newly arranged power box transformer.

[0052] Moreover, the unified grounding system is more conducive to unified maintenance management and state monitoring.

[0053] Figure 3 The structure schematic diagram of the base station machine room lightning protection assembly 100 provided by the embodiment of the application is shown.

[0054] As shown in Figure 3 , the base station machine room lightning protection assembly 100 includes a lightning rod belt 110, a lightning rod net 120, a plurality of structure column down lead wires 130, and a machine room foundation ground net (not shown in the figure), the lightning rod belt 110 is arranged around the roof of the base station machine room 1 in a ring shape, the lightning rod net 120 is installed on the roof of the base station machine room 1 and located inside the lightning rod belt 110; the lightning rod net 120 is electrically connected with the lightning rod belt 110; the structure column down lead wire 130 connects the lightning rod belt 110 with the machine room foundation ground net, and the machine room foundation ground net is electrically connected with the horizontal loop grounding body 410.

[0055] Figure 4 The structure schematic diagram of the lightning rod belt at the first and last joint is shown.

[0056] As shown in Figure 4 , the lightning rod belt 110 is a steel bar connected at the first and last ends, the first end 111 of the lightning rod belt is bent inward to form a pair of butt joints, and the second end 112 of the lightning rod belt is located in the butt joint and welded on the outside of the first end at the butt joint, so that the outside of the lightning rod belt 110 is smooth.

[0057] The end connection mode of the lightning rod belt 110 can ensure the mechanical strength of the lightning rod belt 110, especially the electrical connection reliability of the welding position. In addition, the smooth outer surface is more conducive to construction and is not easy to loosen when subjected to external force.

[0058] Figure 5 The structure schematic diagram of the lightning rod belt at the S-shaped bending part is shown.

[0059] As shown in Figure 5As shown, the lightning receiving belt 110 is provided with at least one S-shaped bending part 113 located near the construction joint of the base station machine room 1; one end of the S-shaped bending part 113 is fixed on one side of the construction joint through a bolt fixing clamp 114, and the other end is fixed on the other side of the construction joint through another bolt fixing clamp 114.

[0060] When the building structure deforms due to temperature or settlement, the S-shaped structure can freely stretch and shrink, avoiding the risk of rigid connection being pulled off and ensuring the continuity of the lightning protection path.

[0061] The lightning protection assembly 100 of the base station machine room further comprises a disconnecting clamp pre-embedded box 140 installed on the structural column of the base station machine room 1, and the disconnecting clamp pre-embedded box 140 is electrically connected with the lightning receiving belt 110 and the machine room foundation ground net through a first special-purpose lead wire; the structural column lower lead wire 130 is one or several structural steel bars in the structural column; the first special-purpose lead wire is consistent with the specification of the structural column steel bar.

[0062] The lightning protection assembly 100 of the base station machine room further comprises a test point connecting steel plate 150 pre-embedded and installed in the structural column of the base station machine room 1, and the test point connecting steel plate 150 is electrically connected with the lightning receiving belt 110 and the machine room foundation ground net through a second special-purpose lead wire; the second special-purpose lead wire is consistent with the specification of the structural column steel bar.

[0063] In some embodiments, the disconnecting clamp in the disconnecting clamp pre-embedded box 140 has a size of 5x50x280mm; the test point connecting steel plate 150 has a size of 10x100x100mm, and the disconnecting clamp and the test point connecting steel plate 150 adopt different sizes.

[0064] In this embodiment, the disconnecting clamp pre-embedded box 140 and the test point connecting steel plate 150 are provided at the same time, and the test objects and system architectures of the two are different; the functions are complementary, and different standards and requirements are met:

[0065] The disconnecting clamp is more to meet the mandatory specifications of building construction acceptance, to prove that the building foundation lightning protection grounding is qualified, and once the acceptance is passed, it is rarely disconnected in the future.

[0066] The test point connecting steel plate 150 is for the operation and maintenance needs of the communication, power and other industries. The operator needs to monitor the condition of the equipment grounding net regularly (such as every year) to ensure that there is no risk, and the test point operation is more convenient and safer, without interrupting the main downlead.

[0067] The double-layer setting of the disconnecting clamp pre-embedded box 140 and the test point connecting steel plate 150 facilitates the testing and maintenance of the natural grounding body and the artificial grounding net in layers.

[0068] In addition, the combination of the two can also provide redundancy and reliability, if one test point is not available due to rust, damage or being buried, the other can be a backup test means, improving the reliability of the entire system maintenance.

[0069] In some embodiments, in addition to the conventional disconnection card, the disconnection card pre-embedded box 140 also integrates a maintenance reminder module. The maintenance reminder module includes a current detection circuit, a timer, a control chip, and a reminder device; the current detection circuit is electrically connected with the disconnection card to detect whether there is current passing through the disconnection card, the control chip is connected with the current detection circuit, and when it is judged that there is current passing through the disconnection card, the timer is activated; the control chip is connected with the reminder device, and the reminder device is activated when the timer counts to the preset value.

[0070] When lightning current passes through the disconnection card or maintenance, the current detection circuit will detect the signal and transmit it to the control chip. The control chip then activates the timer to start timing. When the timing value reaches the preset maintenance period (for example, after a large current impact or after a cumulative number of impacts), the control chip triggers the reminder device (such as an LED indicator or a wireless sending module), sending a maintenance prompt to the maintenance personnel.

[0071] The passive maintenance is changed to active early warning, improving the maintainability and reliability of the system.

[0072] Figure 6 A structural schematic view of the lightning protection assembly for a tower in a first direction is provided for the embodiments of the present application;

[0073] Figure 7 A structural schematic view of the lightning protection assembly for a tower in a second direction is provided for the embodiments of the present application.

[0074] As shown in Figure 6 and Figure 7 The lightning protection assembly 200 for a tower includes a tower foundation ground net 210 located at the bottom of the tower 2 and a plurality of lightning downlead 220 located in the tower 2 column, the tower foundation ground net 210 is electrically connected with the lightning downlead 220; the tower foundation ground net 210 is electrically connected with the horizontal ring line grounding body 410.

[0075] The tower foundation ground net 210 includes a foundation outer ring line and a foundation wiring net located inside the foundation outer ring line, the foundation outer ring line is composed of the outermost layer of reinforcement of the tower 2 bottom structure reinforcement net; every interval of the longitudinal and transverse direction of the tower 2 bottom structure reinforcement net selects a structure reinforcement, all the selected structure reinforcements jointly constitute the foundation wiring net.

[0076] The inherent structural steel bars inside the tower 2 column are used as the lightning down lead 220, which forms a natural parallel multi-path discharge channel with large cross-sectional area, small inductance and low resistance, and can more quickly and smoothly guide the huge lightning current from the top of the tower to the bottom. The structure of the outer ring line + internal ground connection network forms a dense mesh voltage equalizing body at the bottom of the tower 2. When lightning current flows in, it can quickly spread the current to the surrounding soil, greatly reducing the step voltage and touch voltage near the tower 2 foundation, effectively ensuring the safety of maintenance personnel and any animals approaching the tower 2 in rainy weather. The tower foundation ground net 210 is reliably connected with the horizontal ring line grounding body 410 surrounding the entire base station, which makes the grounding of the tower 2 no longer an isolated point, but integrated into the ground net system of the entire base station. This further balances the potential difference between all devices in the base station, fundamentally eliminating damage to sensitive communication equipment.
