Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

The first embodiment is as follows:

referring to fig. 1-3, a robot is used in clearance of self-crawling formula high tension cable snow, including scraping a section of thick bamboo 1, scrape the lateral wall of a section of thick bamboo 1 and seted up race 2, the 2 internal rotations of race is connected with gyro wheel 3, the lateral wall of scraping a section of thick bamboo 1 has seted up ring channel 4, the lateral wall of scraping a section of thick bamboo 1 has seted up two arc walls 11, the 11 internal rotations of arc wall are connected with impeller 12 with the coaxial fixed connection of gyro wheel 3, scrape and install ventilation pipe 13 on a section of thick bamboo 1, and the both ends of ventilation pipe 13 inlay respectively and establish on two arc walls 11 inner walls, install the exhaust apparatus to ventilation pipe 13 exhaust in the ring channel 4.

The exhaust device comprises a spiral coil 5 embedded in an annular groove 4, an air exhaust groove 6 is formed in the side wall of a scraping barrel 1, a magnetic sliding plug 7 is connected in the air exhaust groove 6 in a sealing and sliding mode, a one-way air outlet hole 10 is formed in the sliding plug 7, a one-way air inlet hole 8 communicated with the air exhaust groove 6 is formed in the scraping barrel 1, the one-way air inlet hole 8 limits air to flow into the air exhaust groove 6 from the one-way air inlet hole 8 in a one-way mode, the one-way air outlet hole 10 limits air to flow to one side, close to a guide pipe 9, of the sliding plug 7 from one side, close to the one-way air inlet hole 8, concretely, the reference can be made to figure 1, the one-way air outlet hole 10 can allow the left side of the air sliding plug 7 to flow to the right side of the sliding plug 7, and during actual assembly and manufacturing, a one-way exhaust function can be achieved by installing a one-way valve in the hole.

The air suction groove 6 is communicated with the ventilation pipe 13 through the guide pipe 9, blades of the impeller 12 are made into a wind cup shape, the communicating part of the ventilation pipe 13 and the arc-shaped groove 11 is opposite to the blades of the impeller 12, the rotating directions of the blades of the two impellers 12 are opposite, the rotating directions of the two impellers 12 blown by the ventilation pipe 13 are also opposite, and a reversing valve is arranged at the communicating part of the guide pipe 9 and the ventilation pipe 13, so that the air flow can be controlled to blow to the two arc-shaped grooves 11 through the reversing valve, and the impellers 12 are pushed to rotate, so that the roller 3 rotates forwards or reversely. It should be noted that, because the ac output frequency of the cable 14 is high, the magnetic pole change frequency of the magnetic field induced by the spiral coil 5 is also high, and the high frequency can attract and repel the magnetic sliding plug 7, so that the sliding plug 7 moves back and forth at a high speed, and thus can blow an airflow at a high speed to push the impeller 12 and the roller 3 to rotate, and push the scraper cylinder 1 to move on the cable 14, thereby generating sufficient forward power to clean snow.

The alternating current transmitted by the cable 14 can generate an alternating magnetic field with constantly changing magnitude and direction, and at the same time, the magnetic flux in the spiral coil 5 will constantly change, so that an induced current can be generated in the spiral coil 5 and an induced magnetic field can be generated, and the magnetic poles of the electrified spiral coil 5 are the same as those of the bar magnet, and referring to fig. 1, the magnetic poles are located at two sides in the horizontal direction. When snow on the cable 14 needs to be cleaned in winter, the current transmitted by the cable 14 only needs to be slightly increased, so that the magnetic induction field generated by the spiral coil 5 can attract or repel the magnetic sliding plug 7 to move.

Since the current and the magnetic field of the spiral coil 5 are both induced by the alternating current of the cable 24, the current and the magnetic field of the spiral coil 5 are also in an alternating form in which the magnitude and the direction are constantly changed. When the spiral coil 5 and the magnetic sliding plug 7 repel each other, the sliding plug 7 can be pushed to move to the right, so that air is sucked into the air suction groove 6 along the one-way air inlet hole 8, and when the spiral coil 5 and the sliding plug 7 attract each other, the sliding plug 7 can move to the left, so that the air in the air suction groove 6 is extruded out and flows into the ventilation pipe 13 along the guide pipe 9, and finally the impeller 12 is blown to rotate, so that the roller 3 can be driven to rotate, and finally the scraping cylinder 1 is pulled to horizontally move along the cable 14, so that accumulated snow on the cable 14 can be cleaned.

The direction of rotation of the impeller 12 and the roller 3 can be adjusted by adjusting the direction of flow of the reversing valve to selectively discharge the air discharged from the ventilation pipe 13 from two ports. Therefore, the reversing valve can be controlled by an electromagnetic valve, and the flow direction is changed once at intervals, so that the device moves backwards after moving forwards for a certain distance along the cable 14, the whole cable 14 between the two electric towers can be circularly and repeatedly snow removed, the snow can be effectively prevented from being accumulated on the cable, and the tidy state of the cable 14 can be kept for a long time.

Example two:

referring to fig. 3, different from the first embodiment, scrape a lateral wall fixedly connected with backup pad 18 of section of thick bamboo 1, the first bellows 16 of upper end fixedly connected with of backup pad 18, the upper end fixedly connected with of first bellows 16 shakes ring 17, specifically, can shake ring 17 and slide the setting on scraping a section of thick bamboo 1 lateral wall to it is spacing to shake ring 17, makes to shake ring 17 and can only reciprocate, thereby can carry out effectual the striking to cable 14.

An air supply device for supplying air to the first corrugated pipe 16 is installed in the air extraction groove 6, the air supply device comprises a second corrugated pipe 15 fixedly connected to the inner wall of the air extraction groove 6, the second corrugated pipe 15 is fixedly connected with the sliding plug 7, and the second corrugated pipe 15 is fixedly connected with the first corrugated pipe 16 through an air pipe 19.

In the present embodiment, each time the sliding plug 7 moves to the left, the second bellows 15 is compressed, and air in the second bellows 15 is blown into the first bellows 16, so that the first bellows 16 is extended and pushes the vibration ring 17 to move upwards; when the sliding plug 7 moves to the right, the second bellows 15 is pulled to extend, so that the internal volume of the second bellows 15 is increased, the air in the first bellows 16 can be sucked into the second bellows 15, and therefore the first bellows 16 contracts, and the vibration ring 17 moves downward. The event is at this device operation in-process, and ring 17 that shakes will constantly take place vibration from top to bottom to constantly strike cable 14, make the big piece snow on the cable 14 drop, on the one hand, improve the cleaning efficiency of this device to snow greatly, on the other hand, can effectively reduce the resistance of snow when removing this device, make this device clearance snow more smooth.
