Description
Technical field
The utility model relates to water conservancy and hydropower safety monitoring technology field more particularly to a kind of keeping away for GNSS observation pier
Thunder needle construction.
Background technique
GNSS is typically mounted on engineering slope or dam top as a kind of accurate instrument of surveying and mapping, if without lightning protection measures,
It will directly be damaged after being hit by thunder and lightning, and cause monitoring data loss and economic loss.Current common GNSS preventing thunder measure one
As drawn money on credit strut using 16 stainless steel of Ф production 0.5m~1m, one end is closely connect with GNSS observation pier, and other end installation is taken shelter from the thunder
Needle, lightning rod are higher by GNSS antenna about 1m.The method is although easy to implement, but there are lightning rods and GNSS observation pier apart from mistake
Closely, terminal height is inadequate, when lightning current is grounded aerial drainage by lightning rod, generated induction field reaches antenna,
Intensity does not decay within the scope of safety value, cannot carry out effective protection to GNSS observation pier.
Utility model content
To overcome existing lightning rod because distance GNSS observation pier is excessively close, insufficient height leads to that effective protection cannot be played the role of
The deficiencies of, the technical problem to be solved by the utility model is to provide a kind of lightning protection properties to be preferably used for GNSS observation pier
Lightning-arrest needle construction.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
For the lightning-arrest needle construction of GNSS observation pier, including the installation pedestal beside GNSS observation pier is arranged in and is located at peace
The lightning rod on pedestal is filled, the lightning rod distance GNSS observes 3~4m of pier, and lightning rod top and GNSS observe pier top portion line
Vertical angle be not more than 45 °.
Further, the installation pedestal is equipped with vertical support rod, the lightning rod is arranged in supporting bar top,
Lightning rod is grounded by passing through the cellular conductor of support rod.
Further, the installation pedestal is the entity structure of C20 concreting, and consolidates and connect with matrix.
Further, the cellular conductor and lightning rod access public get access to grid or by insulation sleeve or insulation rubber
It insulate and connects with support rod.
Further, the ground terminal of the cellular conductor accesses the position of underground at least 1m depth by band iron.
The beneficial effects of the utility model are: total is simple and easy, durable reliable, by seeing lightning rod and GNSS
Cha Dun carries out separation arrangement, and reasonable distance and height is arranged, and make lightning rod will not to GNSS antenna while lightning protection
At influence, to preferably protect GNSS antenna.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is existing lightning rod structural schematic diagram.
Label is that 1-GNSS observes pier in figure, and 2- installation pedestal, 3- lightning rod, 4- support rod, 5- lightning rod, α-is vertically
Angle.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1, the utility model includes that the installation pedestal 2 on 1 side of GNSS observation pier is arranged in and is located at installation base
Lightning rod 3 on seat 2, the 3 distance GNSS of lightning rod observe 3~4m of pier, connect at the top of 3 top of lightning rod and GNSS observation pier 1
The vertical angle α of line is not more than 45 °.Traditional lightning rod 5 as shown in Fig. 2, be directly installed on GNSS observation pier 1, due to
Hypotelorism, lightning rod 5 can adversely affect GNSS antenna in the when generated induction field for guiding lightning current.
The utility model is separated by the way that lightning rod 3 is observed pier 1 with GNSS, and controls height and distance, both ensure that
Lightning rod 3 leads thunder effect, and does not interfere with the steady operation of GNSS antenna.Wherein, the height of lightning rod 3 is by itself and GNSS
The distance and top angle α for observing pier 1 determine, are obtained according to theory analysis and test, for distance controlling in 3~4m, angle is not small
Optimal lightning protection effect can be played when 45 °.
Since GNSS observation pier 1 is generally located on engineering slope or dam top, lightning rod 3 is exposed to wind and rain for a long time, is
Its stability and service life are improved, is equipped with vertical support rod 4 in installation pedestal 2 in described state, the lightning rod 3 is arranged
On 4 top of support rod, lightning rod 3 is grounded by passing through the cellular conductor of support rod 4.In order to guarantee the intensity of support rod 4 and resistance to
Long property makes preferably with stainless steel tube.And in order to reduce the magnetic field of lightning current generation and prevent from getting an electric shock, the cellular conductor
It is connected by insulation sleeve or insulation rubber and the insulation of support rod 4 with lightning rod 3.
In order to guarantee that the stability of installation pedestal 2, the installation pedestal 2 are the entity structure of C20 concreting, and with
Matrix is firm to be connected.Entire installation pedestal 2 need to be overall structure, cannot be hollow or intermediate have filler, the size of installation pedestal 2
Control is in a height of 50 × 50 × 25cm of length and width or so.
Thunder effect is effectively led in order to reach, 3 ground resistance of lightning rod and lightning protection resistance should be not more than 10 Ω, in setting
Ground resistance need to be tested, if local soil resistivity is higher, need to take measures on customs clearance reduces direct striking thunder prevention earthing or grounding means ground connection
Resistance, ground connection schemes and should be in conjunction with having buried earth mat and according to field condition Reasonable Arrangement.If having at common ground net, connect
Enter common ground net, if at least 1m depth in underground need to be accessed with ground connection band iron without common ground net.
The utility model overall structure is simple and easy, durable reliable, is separated by the way that lightning rod is observed pier with GNSS
Arrangement, and reasonable distance and height are set, it impact lightning rod will not to GNSS antenna while lightning protection, thus more
Good protection GNSS antenna has good practicability and application prospect.
