The induction cable 1 is coated with the insulating sheath 5, and the insulating sheath 5 does not have conductivity, so that the electromagnetic field change of the induction cable 1 cannot be influenced. Rain water drops on insulating crust 5 in rainy weather, when flowing downwards along insulating crust 5, because the bottom of insulating crust 5 is provided with bar groove 6, low falling down after the edge that the rainwater reachd bar groove 6 avoids forming the cladding water film, avoids forming the electrostatic shield on response cable 1, improves the accuracy of human response when being close to response cable 1 in the rainy weather condition. The width of the upper part of the cross section of the strip-shaped groove 6 is larger than that of the lower part, and when rainwater flows to the edge of the lower end of the strip-shaped groove 6, the rainwater is not easy to flow back to the upper part of the strip-shaped groove 6. The rainwater scraper 7 is arranged on the induction cable 1, rainwater and stains can be scraped by the rainwater scraper 7, and the accuracy of induction when a human body approaches the induction cable 1 is improved.

Specifically, rainwater scaler 7 includes shell 8, non-metal spring 9, first reel 10, drive wheel 11 and scraper blade 12, be equipped with in the shell 8 first reel 10, first reel 10 passes through the drive mechanism drive wheel 11, shell 8 is equipped with scraper blade 12, scraper blade 12 with insulating crust 5 contacts, first reel 10 is equipped with first helicla flute 13, be equipped with ball 14 in the first helicla flute 13, non-metal spring 9 one end is connected with shell 8, and the other end winding is in the first helicla flute 13 of first reel 10, drive rainwater scaler 7 when drive wheel 11 rotates and remove along induction cable 1.

Through rotating first reel 10 and rolling up non-metallic spring 9 on first reel 10, first helicla flute 13 can make the orderly winding of non-metallic spring 9 on first reel 10 for rainwater scaler 7 is stable at power when moving along the wire, makes rainwater scaler 7 scrape water cleaner. After the non-metal spring 9 is wound on the first winding drum 10, the non-metal spring stores power, when the elastic potential energy is released, the driving wheel 11 is driven to rotate through the transmission mechanism, the scraper 12 is in contact with the insulating outer skin 5, and therefore the shell 8 is driven to drive the scraper 12 to move along the insulating outer skin 5 to scrape off rainwater. Be provided with ball 14 in first helicla flute 13, utilize the roll of ball 14 to reduce the frictional force of non-metallic spring 9 on first reel 10, can also slide relatively first reel 10 after non-metallic spring 9 twines on first reel 10, adjust spring's deformation is even, and the dynamics is more even when releasing elasticity, and it is even when shell 8 drives scraper blade 12 and removes to scrape water.

The outer diameter of the second winding drum 15 is smaller than that of the first winding drum 10, and when the nonmetal spring 9 acts on the first winding drum 10 and the second winding drum 15, the moments generated on the first winding drum 10 and the second winding drum 15 are different. Meanwhile, the first winding drum 10 and the second winding drum 15 are provided with chain wheels 17 with the same diameter, and two chain wheels 17 are wound with chains 18, so that under the action of the nonmetal springs 9, the first winding drum 10 rotates to release the nonmetal springs 9, and the nonmetal springs 9 are slowly wound on the second winding drum 15. When the first reel 10 rotates, the driving wheel 11 is driven to rotate, so that the scraper 12 is driven to move to scrape off rainwater. In the case where the non-metal spring 9 is wound on the second reel 15 while being released so that the second reel 15 rotates the same number of times, that is, the driving wheel 11 has the same shape distance, the variation of the elastic force of the non-metal spring 9 is smaller, so that the wiping is uniform and stable when the scraper 12 moves along the insulating sheath 5.

The quantity of the rainwater scraper 7 is two, wherein the first rainwater scraper and the second rainwater scraper are driven to move forward along the insulating outer skin 5 when releasing elastic potential energy, and the second rainwater scraper and the first rainwater scraper are driven to move backward along the insulating outer skin 5 when releasing elastic potential energy, so that water scraping in forward and backward directions is realized. The transmission mechanism is a one-way transmission mechanism 19, when the first winding drum 10 releases elastic potential energy, the driving wheel 11 is driven to rotate, and when the first winding drum 10 winds the nonmetal spring 9, the driving wheel 11 cannot be driven to rotate. When the rain scraper 7 moves to the end of the induction cable 1, the slot 24 of the motor 25 is inserted into the plug 23, and then the motor 25 rotates the first rotating shaft 22 to wind the non-metal spring 9 on the first reel 10 by the engagement of the first conical teeth and the second conical teeth.

Specifically, first reel 10 is installed on dwang 26, dwang 26 one end is rotated with shell 8 and is connected, dwang 26 rotates to the direction that is close to insulating crust 5 under the effect of tension spring 27, dwang 26 one end butt is on the second pivot 29 that has arch 28, first pivot 22 is connected with second pivot 29 through reduction gear 30. When releasing the elastic potential energy, both the first spool 10 and the second spool 15 are rotating. The first reel 10 just releases the elastic potential energy at the end of the predetermined number of rotations of the second reel 15. Before the release of the elastic potential energy is finished, the tension spring 27 pulls the first reel 10 on the rotating lever 26 toward the insulating sheath 5, so that the driving wheel 11 is in contact with the insulating sheath 5.
