By this utility model, solve silo and be easily subject to thunderbolt, it is possible to the problem that silo damages, storing loses can be caused。
Accompanying drawing explanation
By embodiment being described in conjunction with accompanying drawings below, features described above of the present utility model and technological merit will become apparent with easy to understand。
Fig. 1 is the side view of the steel silo lightning protection device according to this utility model embodiment；
Fig. 2 is the top view of the steel silo lightning protection device according to this utility model embodiment。
Detailed description of the invention
The embodiment of steel silo lightning protection device described in the utility model is described below with reference to the accompanying drawings。Those of ordinary skill in the art will be consequently realised that, when not necessarily departing from spirit and scope of the present utility model, it is possible to various different modes or its combination, described embodiment is modified。Therefore, accompanying drawing and description are inherently illustrative, rather than are used for limiting scope of the claims。Additionally, in this manual, accompanying drawing draws not in scale, and identical accompanying drawing labelling represents identical part。
This utility model provides a kind of steel silo lightning protection device, and this device utilizes top, storehouse steel trestle, storehouse top rail to do arrester。Trestle (not shown) is the passage of connection transportation goods and materials, and trestle is by belt feeder transmission material to silo。General trestle is the extreme higher position of Cang Ding, therefore using trestle as arrester, as it is shown in figure 1, thunderbolt imports downlead 3 by trestle, railing。If the position of belt feeder 12 is higher than trestle, then the conductor of belt feeder 12 and trestle are connected, be struck by lightning and import downlead 3 by belt feeder, trestle, railing。
As in figure 2 it is shown, be reliably connected in the place that raft slab muscle 6 connects with reinforcing bar in foundation beam 7, Fig. 2 is connected to 8 places altogether, forms 8 junction points 61,62,63,64,65,66,67,68 so that raft slab muscle 6 is formed with reinforcing bar 7 in the fine strain of millet of basis and is conductively connected。Due to reinforcing bar 7 and the earth reliable conductive in raft slab muscle 6, basis fine strain of millet, therefore, in available raft slab muscle 6 and foundation beam, reinforcing bar 7 does natural grounding substance。
Further, as it is shown in figure 1, one end and the natural grounding substance of pre-embedded bolt connecting-type earth lug 5 are connected；The other end of earth lug 5 is outwards drawn, and is connected with lightning protection downlead 3。
As shown in Figure 1, downlead 3 is surface metallic conductor outside silo wall, downlead 3 is apart from silo outer wall certain distance, it adopts galvanizing round steel to make, upper end and the storehouse top rail of downlead 3 are conductively connected, the lower end of downlead 3 and earth lug 5 are conductively connected, and thus through downlead 3, earth plate 5, natural grounding substance, thunder-strike current are imported the earth from Cang Ding。
The present embodiment adopts 4 downleads 3, as in figure 2 it is shown, downlead 31,32,33,34 is evenly arranged along the circumferencial direction of steel silo。Difference according to silo structure and size, it is possible to there is different arrangements。Further, above connected mode can select conventional welding connecting mode。
By above-mentioned lightning protection device, make full use of the construction features of steel silo, using the electric conductor of storehouse roof construction highest point as natural arrester, using reinforcing bar at the bottom of storehouse as natural grounding substance, simply and effectively solve the thunderbolt of steel silo, it is possible to the problem that silo damages, storing loses can be caused。
According to an embodiment of the present utility model; as shown in Figure 1; for preventing downlead 3 to be subject to mechanical external force damage; downlead 3 position nearer apart from ground adopts protection sleeve pipe 4 to protect; by downlead 3 through protecting in sleeve pipe 4, this protection sleeve pipe 4 can be plastic conduit, and can adopt various material; such as, PC-32 material。It addition, the top of the annular space of protection sleeve pipe 4 and downlead 3 has sealing structure, it is prevented that rainwater etc. are deposited on tube inner corrosion downlead 3, affect lightning protection effect。
In one alternate embodiment, as it is shown in figure 1, downlead 3 has multiple supporting member 2, this supporting member 2 is horizontally arranged between plate storehouse and downlead 3, and one end of this supporting member 2 and the installation bolt 1 of silo connect, and the other end and downlead 3 connect。Supporting member 2 ensure that the intensity of downlead 3 so that it is keeps linear state, conducts thunder-strike current better。
In one alternate embodiment, when adopting welding manner to connect supporting member, the Xian Heban storehouse, one end of this supporting member is installed bolt welding and is integrated, use the installation bolt installing plate storehouse that this connects as one, after the installation of plate storehouse, then the other end and the downlead of supporting member are welded together, due to supporting member plate storehouse install before just with installation bolt welding, therefore, because of welding high temperature, the sealing gasket at installation bolt place, plate storehouse will not be produced impact。
In sum, by steel silo lightning protection device of the present utility model, it is achieved that techniques below effect:
1. the position that downlead is overhead nearer adopts protection casing protection, it is prevented that the mechanical external force damage to downlead；
2. the supporting member of downlead first installs bolt welding with plate storehouse, it is prevented that sealing gasket transconversion into heat, alleviates downlead installation difficulty, improves work efficiency；
3. installing lightning protection device and can avoid field apparatus, personnel are by the damage of natural disaster。
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations。All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model。
