Abstract
The utility model discloses a snake prevention device on an electric power tower. The snake prevention device comprises an annular base and an impeller, wherein the impeller comprises a sleeve and fan blades arranged on the outer sleeve wall of the sleeve; an annular groove is formed in the outer circumference side of the bottom end of the sleeve; the base is arranged in the annular groove. The snake prevention device can be mounted on an existing tower and a stay wire; when a snake climbs to the sleeve along the stay wire, the sleeve rotates, and the snake falls off due to the loss of balance, and in addition, since stronger wind generally exists in the wild, the sleeve can be in rotation under the pushing of the wind, so that a very good snake prevention effect can be achieved, and accidents caused by short circuit are avoided.
Description
Technical field
The utility model relates to power transmission and transformation field, particularly the anti-snake device on electric force pole tower.
Background technology
At present, in China's low-voltage distribution network, generally use cement electric pole.When connecting up, in order to keep the balance of cement pole generally to adopt low anchor bracing wire, i.e. the two ends of bracing wire are separately fixed at cement electric pole and imbed on the distaff of ground wire.Because south China typhoon is more, electric force pole tower generally adopts circle in addition, in lowered in field environment, is easier to be subject to the destruction of the small animals such as snake class.In certain innings of recent 110kv line fault causal investigation, find, because snake is climbed up electric pole top along bracing wire and shines into line switching tripping operation and shine into.As can be seen here, in order to guarantee electrical network reliability service, the anti-snake device of inventing a kind of practicality is necessary.
But in existing this type of patent, complex structure mostly, and in order to prevent the climbing of snake class, at edge, be all provided with sharp keen metal bur, this is to stepping on the injury of bar personnel life safety, also not meeting the principle saving the wild animals.
Utility model content
Technical problem to be solved in the utility model is just to provide the anti-snake device on a kind of electric force pole tower, and simple in structure, cost is low, is applicable to all kinds of electric force pole towers, and anti-snake is effective, neither can damage workmen, also can not injure wildlife.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the anti-snake device on a kind of electric force pole tower, by annular base and impeller, formed, described impeller comprises sleeve and is located at the flabellum on sleeve outer tube wall, described sleeve bottom outer circumferential sides is provided with annular groove, and described base is located in annular groove.
Preferably, described base comprises the housing of two semicircle annulars, and housing oral area outside is provided with lug, and the lug of two semicircle toroidal shells docks and is bolted.
Preferably, described annular groove is for circumferentially one of setting enclosing the U-shaped turnup structure of bending upward along sleeve bottom.
Preferably, described annular groove is for circumferentially one of setting enclosing the V-arrangement turnup structure of bending upward along sleeve bottom.
Preferably, described sleeve cuts open sleeve by two and half and forms by glue is bonding, and described flabellum is connected on sleeve by foldable structure, and the length of described flabellum is 20cm.
Preferably, described housing cross section is U-lag structure, in described housing U-lag, is provided with ball, and described ball bottom is supported in annular groove.
The utility model can be arranged in existing shaft tower and bracing wire, when snake is arranged in pairs or groups on sleeve along bracing wire climbing, sleeve will rotate, snake just drops because of disequilibrium, in addition, in the situation of field, general wind-force is larger, and sleeve can be because the promotion rotation of wind-force, also can play good anti-snake effect, avoid because short circuit has an accident.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the vertical view of impeller;
Fig. 2 is the upward view of base;
Fig. 3 is sleeve and base fit structure schematic diagram.
Embodiment
First in conjunction with Fig. 1 to Fig. 3, the anti-snake implement body structure on electric force pole tower is explained: it is comprised of annular base 2 and impeller 1, described impeller comprises sleeve 10 and is located at the flabellum 11 on sleeve outer tube wall, described sleeve bottom outer circumferential sides is provided with annular groove 101, and described base is located in annular groove.Described base comprises the housing 20 of two semicircle annulars, and the lug that housing oral area outside is provided with 22, two semicircle toroidal shells of lug docks and passes through bolt 23 and fix.Described annular groove is for circumferentially one of setting enclosing the U-shaped turnup structure of bending upward along sleeve bottom.Described housing cross section is U-lag structure, in described housing U-lag, is provided with ball 21, and described ball bottom is supported in annular groove.Described sleeve cuts open sleeve by two and half and forms by glue is bonding, and described flabellum is connected on sleeve by foldable structure, and the length of described flabellum is 20cm, flabellum when stepping on bar personnel operation, be can take in folding.
Certainly, as distortion, described annular groove also can be for circumferentially one of setting enclosing the V-arrangement turnup structure of bending upward along sleeve bottom.
Circular ball is housed in the housing of base, and ball can freely rotate, and its top is positioned at the U-lag of base housing, and bottom directly contacts with the annular groove inwall of sleeve.
Flabellum is equipped with in sleeve outside, and flabellum spacing is proper, and snake cannot pass by force.
In shaft tower or Guywire tower 1m place mounting seat overhead, impeller is installed on base, impeller is hung and is arranged on base by turnup structure.When snake rectilinear creeping, due to flabellum leaf, at nearly shaft tower, to survey spacing less, snake cannot by or be stuck, when snake s is capable while creeping, will touch the distally of flabellum, now can produce a very large moment of torsion flabellum band moving sleeve and rotate, snake will drop because of disequilibrium.In addition,, after field wind-force acquires a certain degree, sleeve can be because the promotion rotation of wind-force also can be played good anti-snake effect.
In application, can adjust the size of ball, the contact-making surface shape of sleeve and base is had a certain degree, the sleeve of guaranteeing to be arranged in different bracing wires can freely rotate.
In addition, the spacing of flabellum and length also can be adjusted according to actual.
