Abstract

FIELD: electricity.

SUBSTANCE: device is in form of hinged and spring levers 1 and 2, on which there are cathode-ray tubes, with a cathode, accelerating anode, screen and an extra cathode and anode on the screen, and a lever 13, joined to lever 1 by a hinge and a spring. On levers 1 and 13 there are also cathode-ray tubes, with a cathode, accelerating anode, screen and an extra cathode and anode on the screen. The cathode-ray tubes are connected to a current source and mounted on levers 1 and 2 and on levers 1 and 13 with provision for repulsion from each other when voltage is applied. On lever 2 there is a gripper. When there are small charges on the screens, electrostatic tubes have large repulsive force.

EFFECT: in comparison to electromagnet, device has little weight, uses less electrical energy; lower expenses on making and using device.

Description

The invention relates to electrical engineering and can be used in robots.

An electrostatic device is known consisting of cathode ray tubes having a cathode accelerating the anode and a screen (L. S. Zhuravlev, V. A. Maranjyan. Physics course. Part Two. Moscow, 1970, p. 280, 281).

Negatively charged cathode ray tube screens repel each other. However, since the screens of this electrostatic device remain negatively charged after repulsion, the cathode ray tubes continue to repel each other. Therefore, such an electrostatic device is unproductive.

The technical result of the invention is to increase the performance of the electrostatic device by removing electrons from the screens of the cathode ray tubes.

The specified technical result is achieved by the fact that on the screens of the cathode ray tubes there are additional anodes and additional cathodes, and the cathode ray tubes themselves are attached to spring-loaded levers connected by a hinge.

Figure 1 shows an electrostatic device, a General view.

Figure 2 shows the levers when the cathode ray tubes do not repel each other, a section.

Figure 3 shows the levers with repulsed from each other by cathode ray tubes, section.

The electrostatic device consists of levers 1 and 2 connected by a hinge 3. The levers 1 and 2 are interconnected by a spring 4. Holders 5 are attached to the levers 1 and 2. Electron beam tubes are located in the holders 5, having casing 6, cathodes 7, accelerating anodes 8, screens 9. On the screens 9 there are additional cathodes 10 and additional anodes 11. A gripper 12 is attached to the lever 2. The lever 1 is connected to the lever 13 by a hinge 14. The levers are connected by a spring 15. The hinge 14 is perpendicular to the hinge 3. To the levers 1 and 13 attached us holders 16, which are inserted in the cathode-ray tube having a housing 17, cathodes, accelerating anodes, screens. On the screens are additional cathodes and additional anodes. The cathode ray tubes are connected by a wire 18 to a current source.

The electrostatic device operates as follows. The operator applies voltage through the wire 18 to the cathodes 7 and to the accelerating anodes 8. The electrons from the cathodes 7 passing through the accelerating anodes 8 reach the screens 9. The screens 9, being charged negatively, are repelled from each other. At the same time, levers 1 and 2 rise. Spring 4 unclenches. Then the operator applies voltage to the cathodes and accelerating anodes of the cathode ray tubes located in the holders 16. The cathode ray tubes repel each other. Levers 1 and 13 diverge. At the same time, levers 1 and 2 are moved. Then the operator applies voltage to the additional cathodes 10 and additional anodes 11. The electrons on the screens 9, starting from the additional cathodes 10, go to the additional anodes 11. The screens 9 freed from the electrons no longer repel each other . Spring 4 attracts levers 1 and 2 to each other. The gripping device 12 captures the subject. So the electrostatic device can capture objects in various places.

Using an electrostatic device of the proposed design will allow you to get the following technical and economic effect. So with small charges on the screens, electrostatic tubes have a large repulsive force. Therefore, an electrostatic device has less weight than an electromagnet and also consumes less electricity. Consequently, its use in robots will reduce the cost of their manufacture and operation.
