Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As depicted in figs. 1 and 2, stem formula fluid driving tube pipeline robot mainly comprises front housing 1, back cabinet 2, rotatingshaft 3, wind wheel 4 and locking mechanism; Wherein: rotatingshaft is arranged on the axial direction of pipeline; The front end of rotatingshaft (passing through bearing) connects front housing rotationally, and the rear end of rotatingshaft connects back cabinet rotationally by reverse-flighted screw mechanism, is also fixing wind wheel on the rotatingshaft; Front housing and back cabinet are positioned at the outer circumferential face of pipe interior and front housing and back cabinet and all make and the matched annulus bodily form of inner-walls of duct shape; Several locking mechanisms are arranged on the outer peripheral surface of front housing and back cabinet.
This wind wheel can utilize the airflow kinetic energy in the pipeline to drive the rotatingshaft rotation; As shown in Figure 2, wind wheel is fixed on the front end of rotatingshaft and is located at the enclosure interior of front housing; As shown in Figure 3, operated by rotary motion has 3 fan blades on the wind wheel.
In this rotatingshaft: the front end of rotatingshaft and rear end are rotatably positioned respectively among mmi machine shell rotation hole 1-1 and the back cabinet rotation hole 2-2; As shown in Figure 5, the front end of rotatingshaft is shaped on two multidiameter shaft 3-2, and multidiameter shaft snaps in the front housing rotation hole; Rotatingshaft also is connected with back cabinet by reverse-flighted screw mechanism; This reverse-flighted screw mechanism comprises: be formed on the reverse-flighted screw 3-1 at rotatingshaft rear portion, the slide block 2-1 that is formed in the back cabinet rotation hole and is slidingly matched with reverse-flighted screw.
As shown in figure 15, two screw threads (being female thread) on the reverse-flighted screw are the first screw thread 3-1-1 and the second screw thread 3-1-2 along the positive and negative layout of whole screw rod, and two screw threads also carry out the smooth transition connection at two of reverse-flighted screw; When rotatingshaft rotates, slide block is driven by first screw thread earlier and slides along reverse-flighted screw axis forward, when sliding into of reverse-flighted screw, because rotatingshaft continues rotation with same direction, slide block is driven along reverse-flighted screw axis reverse slide by second screw thread, so slide block moves back and forth along the reverse-flighted screw axial direction in back cabinet.Described reverse-flighted screw mechanism can directly adopt for existing ripe mechanism.
As shown in Figure 3, offer several on the end face of front housing and be conducive to the vent hole 1-3 that air-flow passes through, so that air-flow promotes the resistance of air that wind wheel rotated and reduced front housing; Also be provided with cavity 1-2 on the front housing, this cavity can place for detection of with the device of service conduit; As shown in Figure 4, be shaped on slide block on the inner peripheral surface of back cabinet rotation hole; As shown in Figure 6, this slide block is the four limit bodily forms, and wherein the side 2-1-1 of two symmetries and the thread engagement of reverse-flighted screw.
Described locking mechanism is used for inner-walls of duct 9 is applied certain resistance, and this resistance can prevent that front housing and back cabinet from retreating (arrow A among Fig. 2 and Fig. 8 is direction of advance of the present utility model) in pipeline; As shown in Figure 3,4 locking mechanisms that all distributing on the outer peripheral surface of front housing and back cabinet; Each locking mechanism comprise the locating slot 5 that is arranged on front housing or the back cabinet outer peripheral surface, rotationally be hinged on convex gear 7 in the locating slot, with the torsion spring 8 of convex gear roof pressure on inner-walls of duct; Pin 6 is used for hinged convex gear, and its axis normal is in the rotatingshaft axis, and torsion spring set is contained on the pin; Convex gear is eccentric segment tooth piece, and tooth limit and swivel pin pitch-row should be towards directions of advance (as shown in Figure 8) from a nearer side; When front housing or back cabinet have the trend that retreats in pipeline, the tooth limit on the convex gear circumferential surface will tightly suppress inner-walls of duct and form bigger surface friction drag, and this surface friction drag helps front housing or back cabinet to keep static relatively in pipeline; When front housing or back cabinet have the trend of advancing in pipeline, convex gear will reduce greatly to the pressure of inner-walls of duct, so the surface friction drag between convex gear and the pipeline also will reduce, and this surface friction drag can not influence front housing or back cabinet advances in pipeline.
Working principle of the present utility model is:
1, original state, as shown in Figure 9: back cabinet is arranged in the left end (figure left direction) of rotatingshaft, and slide block is arranged in first screw thread (plus thread) of reverse-flighted screw; Wind wheel begins to drive the rotatingshaft rotation, driving by reverse-flighted screw mechanism, rotatingshaft pulling back cabinet is drawn close (pulling force B and pulling force B ' act on respectively on front housing and the back cabinet) to front housing, therefore front housing has the trend that retreats with respect to pipeline, and back cabinet has the trend of advancing with respect to pipeline; Keep static on the inner-walls of duct because front housing is positioned at by locking mechanism, back cabinet just advances in pipeline along rotatingshaft;
2, as shown in figure 10, front housing and rotatingshaft are still in the pipeline, and back cabinet is advanced forward in pipeline;
3, state translate phase, as shown in figure 11: this moment, back cabinet was drawn close with front housing, and slide block has slided into the end of reverse-flighted screw first screw thread (plus thread); Because rotatingshaft is rotated further, so slide block slips in second screw thread (left-hand thread) of reverse-flighted screw; As shown in figure 12, driving by reverse-flighted screw mechanism, rotatingshaft will promote back cabinet and break away from front housing (thrust C and thrust C ' act on respectively on front housing and the back cabinet), so front housing has the trend of advancing with respect to pipeline, and back cabinet has the trend that retreats with respect to pipeline; Keep static on the inner-walls of duct because back cabinet is positioned at by locking mechanism, front housing and rotatingshaft just advance along pipeline;
4, as shown in figure 13, back cabinet is still in the pipeline, front housing and rotatingshaft in pipeline to preceding advancing;
5, state translate phase, as shown in figure 14: this moment, back cabinet moved to the left end of rotatingshaft, and slide block has slided into the end of reverse-flighted screw second screw thread (left-hand thread); Because rotatingshaft is rotated further, so slide block slips into again in first screw thread (plus thread) of reverse-flighted screw, and the utility model will continue operation according to the mode of step 1.
Hence one can see that, and the utility model is traveling in the pipeline according to the mode that front housing and back cabinet move forward in pipeline successively.
