The working principle of the system is as follows:

under normal conditions (no thunder and lightning weather), the lightning rod is hidden in the building, dirt cannot be deposited on the surface of the lightning rod, and the lightning rod is convenient to maintain and repair in the building. The electric field monitoring sensor is installed at the top of a building, the sensor device can detect the atmospheric electric field data near the cultural relic protection building in real time, and in the embodiment, the lifting of the lightning rod is determined by the monitored atmospheric electric field data.

In the early days of thunder and lightning, the atmospheric electric field data can be obviously changed, a trigger threshold value can be set, when the monitoring data is continuously greater than the trigger threshold value, the lightning rod can be triggered and controlled to be lifted, and when the monitoring data is continuously less than the trigger threshold value, the lightning rod can be triggered to be lowered.

The building top floor is provided with a through hole, the through hole is provided with a circle of water retaining ring, and the sealing door covers the through hole and forms a sealing structure with the water retaining ring under normal conditions, so that rainwater is prevented from leaking from the through hole. When the lightning rod needs to be lifted, the sealing door is automatically opened, and then the driving mechanism of the lifting platform works. In this embodiment, the driving mechanism includes a driving motor 44, an output shaft of the driving motor 44 has a screw rod 45, a transversely arranged rotating rod 46 is arranged in the lifting table 4, an intermediate gear 47 is arranged in the middle of the rotating rod 46, the screw rod 45 is meshed with the intermediate gear 47, small screw sections are arranged at two ends of the rotating rod 46, and the small screw sections are meshed with the corresponding driving gear 42. The driving motor drives the screw rod to rotate, the middle gear and the rotating rod are driven to rotate through the meshing relation of the screw rod and the middle gear, the two ends of the rotating rod are small spiral sections, and the two driving gears can be driven to synchronously rotate through the meshing relation of the small spiral sections and the driving gears.

In this embodiment, the gear rods are fixed between the guide rail frames on the same side, the guide rail frames are four in number, two on the left and right, and the gear rods are two and located on two sides respectively, that is, two guide rail frames and one gear rod are located on the same side. The inner side edge of the gear rod is provided with a rack, the driving gear is meshed with the rack, the guide rollers of the lifting platform are two-layered, 4 in each layer and correspond to the four guide rail frames, and the lifting platform can smoothly and freely move up and down under the limiting action of the guide rollers and the guide rail frames.

After the lifting platform rises to the highest position, the elastic extrusion ring and the floor slab are extruded to form a sealing structure, the diameter of the floor slab through hole is matched with that of the fixing platform, and when the lifting platform moves to the highest position, the top surface of the fixing platform is higher than that of the water retaining ring, so that rainwater can flow out along the fixing platform and the water retaining ring conveniently, and preferably, the periphery of the water retaining ring 62 is also provided with a circle of slope surfaces 64, so that the rainwater can flow out conveniently. In addition, a sealing ring can be arranged on the inner side of the through hole or the outer side of the fixing table so as to improve the sealing effect between the fixing table and the through hole.

In this structure, each guide rail frame 3 is further provided with an electric bolt 31. When the elevating platform was at highest position, there was the bolt hole on the guide rail frame, and electronic bolt can just in time insert the lower bottom surface to lower floor's guide roller, and electronic bolt plays the supporting role, guarantees the stability of elevating platform.

The lifting rod is controlled to lift in the supporting cylinder in a pneumatic mode, and the lifting rod can ascend and descend by inflation and deflation control of the pneumatic pump. After the lifting rod rises to the highest position, the automatic overturning support, the round rod and the lightning rod are integrally overturned for 180 degrees, so that the lightning rod is vertically upwards. The rotation drive mode this embodiment of support does not do specifically and restricts, and in this embodiment, the lifter top is the upset steering wheel, and automatic upset support is installed to the drive shaft of upset steering wheel on. Of course, the driving mode of the air cylinder and the connecting rod can also be adopted, and the protection scope of the invention is also included.

The lightning rod has the downlead, and the round bar is the hollow tube, draws forth the downlead from the lightning rod, passes the round bar, then stretches out from the round bar lateral wall, support 7 lateral walls and run through fixed station 6, elevating platform 4 positions and all be equipped with insulating protective sheath 93, downlead 81 passes insulating protective sheath 93, there is waterproof cover at the insulating protective sheath top of support section of thick bamboo lateral wall. As a preferable structure, a fixed side frame 74 is arranged at a position, close to the top, of the lifting rod 71, the down conductor 81 is divided into a fixed section and a movable section, wherein one end of the fixed section is connected to the fixed side frame 74, the other end of the fixed section penetrates through the round rod 73 to be connected to a lightning rod, and the end, located at the high position, of the movable section is connected to the fixed side frame 74 and is communicated with the fixed section. The fixed side frame in the structure is used as a middle transition structure of the down lead, the down lead between the fixed side frame and the round rod cannot be pulled, and the lightning rod overturning is not influenced. Because the downlead of fixed section is finally connected to automatic take-up box, when the lightning rod begins to descend, automatic take-up box begins to receive the line, and the line in-process of receiving can produce certain pulling force to the downlead, consequently can provide the connection basis through setting up fixed side bearer, and lightning-arrest influence lightning rod overturns.

When the lifting platform descends to the lowest position, a buffer cushion 21 is arranged on the support frame 2 and at the center of the bottom of the lifting platform 4, and the buffer cushion plays a role of buffering the lifting platform.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
