Abstract
The utility model discloses a bird-proof device for an isolate switch. The bird-proof device for an isolate switch has simple structure, and is formed in one piece by adopt rubbery materials. An upper opening (6) is fixed on the flat surface of the lower end of the base of the isolation switch via a bolt; a universal joint on an operating lever is packaged in a sealing chamber (7), and can freely rotate in the sealing chamber (7). The fit between the operating lever and the opening of the operating lever (4) is the gapped exact fit. The gap between clamp plates (5) is eliminated via the clamping of the bolt to form a sealing entirety, which effectively prevents the birds entering into the gap to build nests. When the bird-proof device for an isolate switch is installed, without the power failure, the bird-proof device for an isolate switch can be changed at any time, and moreover, the flexible operation of the isolation switch can not be influenced.
Description
The utility model belongs to the protector of electric power facility, is used in particular for the bird-proof device of outdoor high-voltage isolating switch, and what be effective stops the trouble that sparrow is built nest.
The operation hole of existing outdoor high-voltage isolating switch generally is open type, and sparrow is nested by the gear box inside that base aperture enters into isolating switch.Cause mechanical jam, fault such as transmission is malfunctioning, real is the great trouble of power transformation operation.
The purpose of this utility model provides a kind of simple in structure, can prevent effectively that again sparrow from entering isolating switch inside and nesting, and can keep the cleaning of rotary part, flexibly.
The purpose of this utility model reaches like this, and the housing of this device gap location by clamping plate is sleeved on the joystick, and fixing hole suitable for reading cooperates with base aperture, and with bolt.With the fastener hole bolt on the clamping plate, following joystick hole cooperates with the joystick precise gaps, and universal joint wraps in the closed chamber.So just formed seal isolation with the external world.Having prevented effectively that sparrow from entering in the gear box of isolating switch nests.And can keep rotating part to clean the universal energy-conservation freedom of in closed chamber, rotating, joystick also can rotate in the joystick hole and the isolating switch integral installation ties in, and has not only ensured the flexible of isolating switch normal running, and novelty attractive in appearance.
The utility model has the advantages that simple in structurely, housing adopts the natural rubber time processing moulding of special formulation, can keep softness characteristics to be adapted to the natural environment of China's wide geographic area in-30 ℃ to+40 ℃ temperature.In addition, by dress the time, need not to have a power failure, can be at any time by dress replacing, maintenance.
Below accompanying drawing is done brief description.
Fig. 1 is the front view of this device.It among the figure revolved sectional view along the A-A section among the figure worker.
Fig. 2 is the attached view of this device.
Have in the accompanying drawings: housing (1), fixing hole (2), fastener hole (3), joystick hole (4) clamp and pull (5), (6) suitable for reading, closed chamber (7).
Below in conjunction with specific embodiment accompanying drawing is explained in detail.
This device is applied to outdoor high-voltage isolating switch, at the universal joint place of the joystick of switch separately and be inserted in two clamping plates (5) of housing (1), two screwed holes on the base aperture on the fixing hole of (6) suitable for reading (2) and the switch align, and are fixed with bolt.Universal joint and joystick are promptly wrapped in it within closed chamber (7) by housing (1).After the external diameter that clamping plate (5) clamp lever hole (4) is slightly larger than joystick when free with bolt clamped, joystick can rotate within it, and (1) distortion that do not make housing.Universal joint can freely rotate in closed chamber (7) after shell (1) clamps.(6) suitable for reading on the housing (1) cooperate the opened gap of clamping plate (5) to clamp the back closing seam by bolt with the baseplane of the base aperture of switch, joystick hole (4) are gapped accurate the cooperation with joystick.Like this, whole base aperture has just been sealed fully by this device.Thereby stoped entering of sparrow.
The housing of bird-proof device of the present utility model (1) is the overall structure of elastomeric material system.Gap between two clamping plates (5) is generally 0,2～1,5 millimeter, and the wall thickness of shell (1) is 1～5 millimeter.
Claims (1)
1, a kind of bird-proof device that is used for outdoor high-voltage isolating switch, the housing (1) that it is characterized in that this device is the integral body of tubular, fixing hole (2) is arranged on (6) suitable for reading, four fastener holes (3) are arranged on the clamping plate (5), a joystick hole (4) and a columniform closed chamber (7) are arranged below.
