In this embodiment: the arrangement of the asphalt enhances the corrosion resistance of the surfaces of the first pipeline 1 and the second pipeline 4, and the fluorescent powder is added in the manufacturing process of the asphalt, so that passers can clearly observe the positions of the first pipeline 1 and the second pipeline 4 at night.
The working principle and the using process of the invention are as follows: when water flows into the first pipeline 1 from the two flow channels 101 and is acted by water pressure, the first sealing plate 112 and the second sealing plate 113 are respectively bent inward along the central axis of the rotating rod 104 by an angle, and are under elastic tension of the torsion spring 114, two ends of the torsion spring 114 respectively abut against the side ends of the first sealing plate 112 and the second sealing plate 113 to keep the first sealing plate 112 and the second sealing plate 113 in a horizontal state, the first sealing plate 112 and the second sealing plate 113 respectively block the two flow channels 101 after the water flow weakens or disappears, so that the first pipeline 1 is in a closed state and also prevents the water flow from flowing back in the opposite direction, when parts of the check valve mechanism are damaged, the motor 109 is started through an external connection signal, the motor 109 drives the gear 111 to rotate, the gear 111 is meshed and connected with the rack 106, and therefore drives the second slider 105 to slide on the inner wall of the sliding slot 102, so as to drive the rotating rod 104 to move the first sealing plate 112 and the second sealing plate 113 away from the two flow channels 101, at this moment, the two flow channels 101 can be completely opened to the channel in the direction of the first pipeline 1, and the limiting block 107 is touched to be completely static after the two flow channels are moved for a certain distance, the gear 111 is prevented from being touched by excessive displacement of the rotating rod 104, under the condition of needing multiple sealing, the telescopic machine 207 is started, the output shaft of the telescopic machine 207 drives the damping block 208 to move downwards, the descending process of the third sealing plate 209 is stable under the action of elastic tension of the damping block 208, the third sealing plate 209 penetrates through the groove 204 and then is inserted into the gap between the first connecting block 2 and the second connecting block 3, the interval between the first connecting block 2 and the second connecting block 3 is the same as the thickness of the third sealing plate 209, and then the bottom end of the third sealing plate 209 abuts against the bottom plate 201 and can completely seal the channels of the first connecting block 2 and the second connecting block 3.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the invention as defined by the appended claims. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
