Specific implementation mode
The utility model is described in further detail below by specific implementation mode：
Reference numeral in Figure of description includes：Inner ring 1, outer shroud 2, connecting rod 3, center ring 4, lamppost 5.
As shown in Figure 1, some outdoor landscape lamps are mounted on the place of no equipotential bonding, while TT systems cannot be used again
(such as garden landscape lamp at the top of basement), is readily incorporated false voltage, increases the danger of electric shock.Electricity are always waited when no
When earth fault occurs for the L3 phases that position is coupled, Id=220V/ (Rb+Rc) then generates a false voltage Ud=on PE lines
Id*Rb, the false voltage are conducted by PE lines to Landscape Lamp lamppost, at this moment if someone contacts the shock hazard of lamppost meeting.
The generation of motor accident in order to prevent, applicant have developed Landscape Lamp equipotential device as shown in Figure 2.
As shown in Figures 2 and 3, Landscape Lamp equipotential device includes being extended radially out for welded with lamppost 5 four
Connecting rod and be the center of circle from the interior inner ring 1 being coaxially disposed outward and outer shroud 2 with lamppost 5.Inner ring 1 and outer shroud 2 are welded on
In four connecting rods 3, wherein outer shroud 2 is welded with the one end of all connecting rods far from lamppost 5.Inner ring 1 is welded on lamppost 5 and outer
Between ring 2.Connecting rod, inner ring 1 and outer shroud 2 are made of the material of conductive energy, connecting rod, inner ring 1 in the present embodiment
With outer shroud 2 by energy conductionGalvanized steel bar is made.Steel has good electric conductivity and load-bearing capacity, can not only be effectively by lamp
Electric current on column 5 is transmitted, additionally it is possible to which installation is trampled for pedestrian on the ground.It is zinc-plated, it can prevent steel from being aoxidized, extension makes
Use the time.
Angle between two neighboring connecting rod 3 is 90 degree.Four connecting rods 3 are evenly distributed on the surrounding of lamppost 5, phase
Angle between adjacent two connecting rods 3 is 90 degree, each connecting rod 3 can be made to be connect with lamppost 5, while can make connection again
Bar 3 constructs a similar netted foot pedal structure with inner ring 1, outer shroud 2 together, makes anyone that can step on equipotential at this
On foot pedal structure, electrical shock hazard is avoided.In addition, such setting can save the number of connecting rod 3 to the maximum extent, material is saved
Material.
The annulus that the radius of outer shroud 2 is 580 millimeters to 620 millimeters.The step pitch of adult is 450 millimeters to 650 millimeters
Between, the radius of outer shroud 2 is arranged between 580 millimeters to 620 millimeters, can make most of adults under by Landscape Lamp
It can be entered into when square on Landscape Lamp equipotential device, make one to lead to safely in the equipotential region that equipotential device constructs
Cross the region below Landscape Lamp.In order to meet the step pitch length of nearly all adult, the radius of outer shroud 2 is chosen to be 600 millis
Rice, in order to facilitate the installation of, by the two semicircular ring welded connections of outer shroud 2.
The annulus that the radius of inner ring 1 is 280 millimeters to 320 millimeters.The step pitch of adult is 450 millimeters to 650 millimeters
Between, the radius of inner ring 1 is equivalent to the half of people's step pitch, can not only ensure that adult enters into Landscape Lamp equipotential device
On, it has also fully considered the step pitch of child, in conjunction with the connecting rod 3 of radial arrangement, has made child that can also enter into Landscape Lamp equipotential
In device, when lamppost 5 being avoided to leak electricity because potential difference and caused by electrical shock hazard.In order to meet nearly all adult's
The step pitch length of step pitch length and most of children that can be walked, is chosen to be 300 millimeters by the radius of inner ring 1, pacifies for convenience
Dress, by inner ring 1 also with two semicircular ring welded connections.
For equipotential device by the way that in welded connection to lamppost, wherein inner ring 1 is 300 millimeters of radiuses, outer shroud 2 is 600 millimeters
Radius.Directly four connecting rods can be welded on lamppost 5.Positioning to connecting rod for convenience, makes connecting rod and lamppost 5
Connect more securely and in order to meet 5 connection requirement of lamppost of various different radiis, it can be in connecting rod close to the one of lamppost 5
An arc block is welded on end, all arc blocks are closed up on same circumference.All arc blocks close up composition energy
Enough it is close to surround the center ring 4 of lamppost 5.By center ring 4, equipotential device can be made to be connect with lamppost 5 more secured
Stablize.
As shown in Fig. 2, equipotential device is embedded in 50 millimeters away from below ground hereinafter, simultaneously and lamppost when installation Landscape Lamp
It is reliable to be coupled, in this way, lamppost and equipotential device are in equipotential state.If on B points, hand contacts A at someone station at this time
The current potential of point, point-to-point transmission is of substantially equal, can effectively prevent shock hazard.
By the connecting rod 3 being connect with lamppost 5, the electric current on lamppost 5 is transmitted in connecting rod 3, by with connecting rod 3
The inner ring 1 and outer shroud 2 of connection, the electric current in connecting rod 3 is transmitted in inner ring 1 and outer shroud 2, makes lamppost 5, connecting rod 3, inner ring
1 and outer shroud 2 on current potential it is all equal.Lamppost 5 is touched when people station is in inner ring 1, outer shroud 2 or connecting rod 3, because of people
2 points of body contact have same potential, not will produce potential difference, therefore not will produce shock phenomenon.
When Landscape Lamp can not use TN-S system power supplies using TT systems, PE lines have the possibility for introducing false voltage
Property, the danger of electric shock can be carried, the case where Landscape Lamp equipotential device makes human body and lamppost be in same current potential, effectively prevent electricity
Hit danger.
Above-described is only the embodiments of the present invention, and the common sense such as well known concrete structure and characteristic are herein in scheme
It does not describe excessively.It should be pointed out that for those skilled in the art, in the premise for not departing from the utility model structure
Under, several modifications and improvements can also be made, these should also be considered as the scope of protection of the utility model, these are not all interfered with
