Abstract
The utility model discloses an emergency power supply vehicle grounding device which includes a grounding wire and a grounding rod which is connected with the grounding wire. The device also includes a coiling shaft disk which includes a coiling roller, a handle and a roller shaft. The roller shaft is connected with a metal housing of a power generator. The coiling roller is connected with the grounding wire. A conductive path is arranged between the metal housing of the power generator and the grounding wire. The emergency power supply vehicle grounding device has the characteristics of simple structure, low production cost, and convenience of use. The grounding wire can be collected and released through rotating the coiling shaft disk, so the operation is convenient, the collection and release are easy, and the identification is easy.
Description
Technical field
The utility model relates to a kind of protective earthing device, especially a kind of protective earthing device of emergency service car.
Background technology
When the emergency service car carried out homework of supplying power at the power failure scene, its metal partly need to carry out reliably protective earthing.Especially have in the test that high voltage produces at dielectric voltage withstand etc., earth connection reliably ground connection playing is guaranteed the important function of equipment normal operation and protection test personnel life security.Protect in the electric operation emergent, the staff often will carry sufficiently long earth connection.All the time, earth connection is rolled into a ball into one in the emergency service car, and neither neat appearance is easily disorderly, pretty troublesome during use again, also dallies over one's work the time.Traditional earth connection only has earth rod a kind of at earthing mode, and the range of application of emergency service car mostly is stadiums in the urban district, Conference Room etc.Therefore and the ground in these places mostly is hard surface, can not adopt conventional earth electrode to pound earthing mode into ground.
The utility model content
The technical problems to be solved in the utility model provides a kind of emergency service car earthing device, it have simple in structure, cost of manufacture is low, the characteristics such as easy to use.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: it comprises earth connection and is attached thereto the earth rod that connects, it also comprises a coiling reel in addition, the coiling reel comprises winding roller, handle and roll shaft, roll shaft is connected with the generator metal shell, winding roller is connected with earth connection, is provided with conductive path between generator metal shell and the earth connection.
The utility model further improves and is: conductive path is: the material of winding roller and roll shaft is metal material; The material of winding roller and roll shaft is copper; Roll shaft is fixedly connected with generator metal shell screw thread by the connecting plate with connecting hole that the roll shaft end arranges; The earth terminal of earth connection is connected with earthing clamp.
The beneficial effect that adopts technique scheme to produce is: after the protective earthing line increases the coiling reel, can carry out folding and unfolding by earth wire by rotation coiling reel, easy to use, easily receipts are easily put, easily identification.Originally need two setting-out works that the people finishes, and only needed now a people easily to finish, improved operating efficiency; The earth terminal of earth connection has increased earthing clamp, direct ground connection on the existing earth electrode at the scene, optimize the emergency service turner and made the earthing mode of ground connection, solve hard surface and used earth rod ground connection hard problem, make ground connection work convenient, improved equipment and staff's fail safe.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of coiling reel among Fig. 1.
In the accompanying drawings: 1, winding roller; 2, handle; 3, roll shaft; 4, connecting plate; 5, earth connection; 6, generator metal shell; 7, earth rod; 8, earthing clamp.
Embodiment
By the embodiment shown in Fig. 1-2 as can be known, it comprises earth connection 5 and is attached thereto the earth rod 7 that connects, it also comprises a coiling reel in addition, the coiling reel comprises winding roller 1, handle 2 and roll shaft 3, roll shaft 3 is connected with generator metal shell 6, winding roller 1 is connected with earth connection 5, is provided with conductive path between generator metal shell 6 and the earth connection 5; Conductive path is: the material of winding roller 1 and roll shaft 3 is copper; Roll shaft 3 is fixedly connected with generator metal shell 6 screw threads by the connecting plate 4 with connecting hole that roll shaft 3 ends arrange; The earth terminal of earth connection 5 is connected with earthing clamp 8.
Conductive path can also be designed to: roll shaft is metal material, and winding roller is non-metallic material, and in the fixing conduction brush of winding roller, conduction brush and roll shaft contact, and ground wire is connected with conduction brush.
Using method:
The emergency service car is before homework of supplying power, by rotation coiling reel the earth terminal of earth connection is put position to suitable ground connection first, carry out reliably ground connection by earth rod or earthing clamp again, after homework of supplying power finishes, by rotation coiling reel earth connection is regained again, by adopting coiling reel earth wire to carry out orderly folding and unfolding, the earth connection of having avoided growing makes earth connection neat appearance in the emergency service car because of the random line phenomenon that unordered folding and unfolding causes.
