Right shell body 21 ' is also semicylindrical working of plastics, is also respectively equipped with end cap at the two ends of right shell body, is also respectively equipped with the first closing in and second closes up at the center of two end cap.The external diameter of right shell body is identical with the external diameter of left shell, and after the end contact of left shell and right shell body, left shell and right shell body form a cylinder.Right shell body is also provided with wire casing and string holes, and as shown in Figure 8, in the wire casing of right shell body, be also provided with a screwed hole 27, screwed hole is between two lines.Except screwed hole 27, left shell is identical with the architectural feature of right shell body.
As shown in Figure 3, the inwall of left shell is provided with a retainer ring 4, retainer ring is the working of plastics of racetrack, as shown in Figure 10, in the inner chamber of retainer ring, be provided with a cushion block 52, the installation end of cushion block is fixed on the circular arc inwall of left shell, and cushion block can adopt working of plastics, now the effect end of cushion block is plane, is obtained by injection moulding.Cushion block also can be plastic foam, and now cushion block is bonded on left shell inwall.Cushion block also can be made up of cloth and sponge, and cloth is wrapped in the outside of sponge, cloth is bonded on left shell.Parachute is propped up in acting as of cushion block, to ensure that parachute is normally opened.The umbrella rope 51 of parachute 5 ties up on the inwall of left shell, and retainer ring is surrounded by the installation end of some umbrella ropes.As shown in figure 11, when left shell is from placement in height, parachute is opened, and left shell is played to the effect of deceleration, reduces impulsive force when left shell lands.The inwall of right shell body is also provided with retainer ring, parachute and cushion block, and the shape of retainer ring on left and right housing, parachute and cushion block, structure are identical.
The end cap on left shell top is provided with secant assembly 6, secant assembly comprises micromachine 60, gear 61, tooth bar 62, blade 63 and support 64, as shown in Figure 4, the inwall of end cap is fixed with support 64, support is rotatablely equipped with gear 61, and gear is fixed on micromachine 60 output shaft that is positioned on end cap inwall, and support is slidably fitted with a tooth bar 62, rack and pinion engagement fit, the other end of tooth bar is fixed with blade 63.By minitype motor driving pinion rotation, and then realize the rectilinear movement of tooth bar, blade is provided with the blade 631 of inclination.After the end contact of left shell and right shell body, left shell is mutually corresponding with two string holes on right shell body and be divided into two right, and the string holes coaxial line of correspondence is arranged, and the string holes axes normal of correspondence is in blade.The end cap on right shell body top is also provided with secant assembly, and wherein a pair string holes is corresponding with the secant assembly on left shell, and another is corresponding with the secant assembly on right shell body to string holes.Micromachine is connected with storage battery by wire, is arranged on left and right housing after storage battery being full of electricity.Also can arrange solar panel on left shell and right shell body, solar panel is connected with storage battery, and storage battery is electrically connected with micromachine.
Secant assembly is positioned at the side of the left shell plane of symmetry, is the weight of balance secant assembly, as shown in figure 12, is provided with balancing weight 7 at the opposite side of the left shell plane of symmetry.When falling to prevent left shell, left shell is about the rollover of the plane of symmetry.Right shell body is also provided with balancing weight, rollover phenomenon when can prevent right shell body from falling.As shown in figure 13, during use, by left shell and right shell body to together with, then a binding wire 8 is passed two pairs of string holes successively, by binding wire by left shell together with right shell body string, now binding wire becomes a U-shaped lain low, and shell is stretched out through after the string holes on right shell body in the two ends of binding wire.The setting of wire casing can be convenient to the cabling of binding wire, and binding wire is close in wire casing.For being realized the relative fixing of left shell and right shell body by binding wire, as shown in figure 15, be fixed with expand block 82 in one end of binding wire, the external diameter of block of expanding is greater than string holes aperture.The other end of binding wire is stretched in screwed hole, and as shown in figure 14, in screwed hole, screw thread is provided with bolt 81.
Realize the fixing of left shell and right shell body by binding wire, now binding wire is in tensioned state.As shown in figure 16, rotated clockwise by micromachine driven wheel, and then the rectilinear movement of band carry-over bar, finally realize the rectilinear movement of blade, blade is in moving process, the blade of blade is gradually near binding wire, and after the blade of blade contacts with binding wire, blade cuts off operation to binding wire gradually.Two secant assemblies work simultaneously, and as shown in figure 17, binding wire cuts off by the blade 63 in two secant assemblies and blade 63 ' substantially simultaneously.As shown in figure 18, binding wire is divided into three sections, and now binding wire is fixedly connected with event resolves to left shell and right shell body, and left shell and right shell body are separately.Because balancing weight and secant assembly quality are comparatively large, the top of left and right housing just can be driven to fall, the top of left and right housing, when falling, overcomes the adhesion of solid gum or VELCRO, makes the bottom of left and right housing separate and fall.First close up and between composite insulator, second close up and be respectively equipped with rubber ring 9 between composite insulator, rubber ring is cylindric, rubber ring the frictional force that can increase between composite insulator and shell is set, prevent shell along the downslide of composite insulator.As shown in Figure 2, circular cone 3 is respectively equipped with at the top of left shell and the top of right shell body, the large end of circular cone is placed in top, the small end of circular cone is placed in bottom, as shown in figure 19, be arranged on composite insulator by anti-unfirmly closing device, the angle β between two anti-unfirmly closing devices is less than angle α, now, can prevent bird from dropping between two composite insulators.
Micromachine in two secant assemblies and remote controller wireless telecommunications, by remote controller control two micromachines action and stopping, rotating forward and overturn.During use, first left shell and right shell body are arranged on composite insulator, then composite insulator are arranged on steel tower, after this experience one transmission line uncharged period.During this period, the setting of shell and circular cone, can prevent from small bird from dropping on composite insulator pecks hindering power circuit.When needs are energized, signal is sent to micromachine by remote controller, make micromachine action, movement with cutting blade is to cut off the binding wire that left shell and right shell body are fixed in colligation, now, under the effect of secant assembly and balancing weight, left shell and right shell body fall from composite insulator, and do not need people to climb on steel tower to remove shell, avoid workload and the potential safety hazard brought of climbing that people climbs.Before mounting casing, first parachute and left and right inner walls are sticked together by adhesive tape, during mounting casing, remove adhesive tape.
